Java is a robust, object-oriented programming language expressly designed for use in the distributed environment of the Internet. Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network. A source program in Java is compiled into byte code, which can be run anywhere in a
DETAILED DESCRIPTION 25
A Java application stack includes a Java layer 5 for running any one of multiple different applications. In one example, the applications are related to different vehicle operations Such as Infrared (IR) and radar sensor control and monitoring,
network on a server or a client that has a Java virtual machine
(JVM). AJVM describes software that is nothing more than an inter face between the compiled byte code and the microprocessor or hardware platform that actually performs the programs instructions. Thus, the JVM makes it possible for Java appli cation programs to be built that can run on any platform without having to be rewritten or recompiled by the program mer for each separate platform. Jini is a distributed system based on the idea of federating groups of users and the resources required by those users. Resources can be implemented either as hardware devices, Software programs, or a combination of the two. The Jini system extends the Java application environment from a single virtual machine to a network of machines. The Java application environment provides a good computing platform for distributed computing because both code and data can move from machine to machine. The Jini infrastructure pro vides mechanisms for devices, services, and users to join and detach from a network. Jini systems are more dynamic than is currently possible in networked groups where configuring a network is a centralized function done by hand. However, the Java/Jini approach is not without its disad Vantages. Both Java and Jini are free, open source applica tions. The Java application environment is not designed for controlling messaging between different machines. For example, the Java application is not concerned about the protocols between different hardware platforms. Jini has some built-in security that allows code to be downloaded and
implemented in the same JVM 10, However, for explanation purposes, the JVM 10 and the SRE 14 will be shown as separate elements. FIG.2 shows a system 15 that includes multiple processors 16, 18, 20, 22 and 24. Each processor includes one or more JVMs 10 that run different Java applications. For example, processor 16 includes one Java application 28 that controls a vehicle security system and another Java application 26 that controls the vehicles antilock brakes. A processor 18 includes a Java application 30 that controls audio sources in the vehicle. Other processors 20 and 22 may run different threads 32A and 32B for the same sensor fusion Java application 32 that monitors different IR sensors. Another thread 32C on
SUMMARY OF THE INVENTION
The present invention allows construction of a secure, real time operating system from a portable language such as Java that appears to be a Java virtual machine from a top perspec
A Java Virtual Machine (JVM) layer 16 provides the hard ware independent platform for running the Java applications 5. A Jini layer 12 provides some limited security for the Java applications that run on different machines. However, the Jini layer 12 does not provide the necessary reconfiguration and security management necessary for a distributed real-time multiprocessor system. A Secure Real-time Executive (SRE) 14 provides an exten sion to the JVM 16 and allows Java to run on different pro cessors for real-time applications. The SRE 20 manages mes saging, security, critical data, file I/O multiprocessor task control and watchdog tasks in the Java environment as described below. The JVM 16, Jini 12 and SRE 14 can all be
run from different machines in confidence. However, this
limited security is insufficient for environments where it is necessary to further restrict code sharing or operation sharing among selected devices in a secure embedded system.
vehicle brake control, vehicle audio and video control, envi ronmental control, driver assistance control, etc.
processor 24 monitors a radar sensor for the sensor fusion Java application 32. The SRE 14 runs below the JVMs 10 in each processor and control tasks, messaging, security, etc. For example, the Java application 26 controls vehicle braking according to the sen sor data collected by the sensor fusion Java application 32. The SRE 14 in one example prevents unauthorized data from being loaded into the processor 16 that runs brake control application 26. The SRE 14 also prevents other Java applica tions that are allowed to be loaded into processor 16 from
US 8,020,028 B1 3 disrupting critical braking operations, or taking priority over the braking operations, performed by Java application 26. For example, the SRE 14 may prevent noncritical vehicle applications, such as audio control, from being loaded onto processor 16. In another example, noncritical operations, Such as security control application 28, are allowed to be loaded onto processor 16. However, the SRE 14 assigns the security messages low priority values that will only be pro cessed when there are no braking tasks in application 26 that require processing by processor 16. The SRE 14 allows any variety of real-time, mission criti cal, nonreal-time and nonmission critical Java applications to be loaded onto the multiprocessor system 15. The SRE 14 then automatically manages the different types of applica tions and messages to ensure that the critical vehicle applica tions are not corrupted and processed with the necessary priority. The SRE 14 is secure software that cannot be manipulated by other Java applications. The SRE 14 provides priority preemption on a message scale across the entire system 15 and priority preemption on a task scale across the entire system 15. So the SRE 14

However, Some specific tasks performed by the managers 50-60 are described below in further detail.
such as a Universal Serial Bus, a wireless link such as blue tooth or IEEE 802.11, or a network link such as Ethernet, etc.
The configuration manager 60 acts as a watchdog to make
sure that the GPS thread 62 and the sensor fusion thread 64 are
controls how the JVMs 10 talk to each other and controls how
the JVMs 10 are started or initiated to perform tasks. The SRE 14 allows programmers to write applications using Java in a
safe and secure real time environment. Thus, viruses can be
prevented by SRE 14 from infiltrating the system 15. While the explanation uses Java as one example of a pro gramming environment where SRE 14 can be implemented, it should be understood that the SRE 14 can be integrated into any variety of different programming environments that may run in the same or different systems 15. For example, SRE 14 can be integrated into an Application Programmers Interface (API) for use with any programming language such as C++. FIG.3 shows the different functions that are performed by the SRE 20. Any combination of the functions described below can be provided in the SRE20. A message manager 50 controls the order messages are received and transmitted by the different Java applications. A security manager 52 con trols what data and messages are allowed to be received or transmitted by different Java applications. A critical data manager 54 controls what data is archived by the different Java applications. A data manager 56 controls what data is allowed to be transferred between different processors. A task manager 58 controls the order tasks are performed by the different JVMs. A reconfiguration manager 60 monitors the operation of the different processors in the system and reassigns or reconfig ures Java applications and Java threads to different processors according to what processors have failed or what new proces sors and applications have been configured into system 15. The message manager 50 partially corresponds to the pri ority manager 44 shown in FIG. 2 of pending patent applica tion Ser. No. 09/841,753, the critical data manager 52 par tially corresponds with the logging manager 44 shown in FIG. 2 of the copending 753 patent application, and the security manger 54 a least partially corresponds with the security manager 40 shown in the 753 patent application. The data manager 56 at least partially corresponds with the data man ager 42 shown in FIG. 2 of pending patent application Ser. No. 09/841,915, the task manager 58 partially corresponds to the device manger 46 shown in FIG. 2 of the 915 application, and the configuration manager 60 at least partially corre sponds to the configuration manager 44 shown in FIG. 2 of the 915 patent application. The descriptions of how the different managers 50-60 operate similarly to the corresponding man
FIG. 4 shows in more detail how the SRE 14 operates. One of the operations performed by the task manager 58 is to control when different tasks are initiated on different proces sors. For example, a first Global Positioning System (GPS) thread 62 is running on a JVM in a processor 80. Another sensor fusion thread 64 is running on a different processor 82. Block 74 represents the Java Virtual Machine operating in each of processors 80 and 82. A master JVM 74 may run on either processor 80, processor 82 or on some other processor. The task manager 58 sends an initiation command 66 to the GPS thread 62 to obtain location data. The task manager 58 then directs the obtained GPS data 68 through a link to the sensor fusion thread 64 for subsequent processing of GPS data 68. The link may be any bus, such as a PCIbus, serial link
each running correctly. In one example, separate configura tion managers 60 in each processor 80 and 82 sends out periodic signals to the other configuration managers 60 in the other processors. Any one of the configuration managers 60 can detect a processor or application failure by not receiving the periodic 'ok' signals from any one of the other processors for some period of time. If a failure is detected, then a par ticular master configuration manager 60 in one of the proces sors determines where the task in the failed processor is going to be reloaded. If the master configuration manager 60 dies, then some conventional priority Scheme, such as round robin, is used to select another configuration master. If a failure is detected, say in the processor 82 that is currently performing the sensor fusion thread 64, a message is sent from the configuration manager 60 notifying the task manager 58 which processor is reassigned the sensor fusion thread. In this example, another sensor fusion thread 76 in processor 84 is configured by the configuration manager 60. The critical data manager 52 manages the retention of any critical data 72 that was previously generated by the sensor fusion thread 64. For example, the critical data manager 54 automatically stores certain data and state information that was currently, being used in the sensor fusion thread 64. The critical data may include GPS readings for the last 10 min utes, sensor data obtained from sensors in other processors in the vehicle over the last 10 minutes. The critical data may also include any processed data generated by the sensor fusion thread 64 that identifies any critical vehicle conditions. The critical data manager 52 also determines which data to archive generally for vehicle maintenance and accident reconstruction purposes. The configuration manager 60 directs the critical data 72 to the new sensor fusion thread 76. The task manager 74 then redirects any new GPS data obtained by the GPS thread 78 to the new sensor fusion thread 76 and controls sensor fusion
tasks from application 76. Thus, the configuration manager 60 and the task manager 58 dynamically control how different Java threads are initialized, distributed and activated on dif
ferent processors. The message manager 50 determines the priority of sent and received messages. If the data transmitted and received by the sensor fusion thread 76 is higher priority than other data transmitted and received on the processor 84, then the sensor fusion data will be given priority over the other data.
US 8,020,028 B1 5 The task manager 58 controls the priority that the sensor fusion thread 76 is giving by processor 84. If the sensor fusion thread 76 has higher priority than, for example, an audio application that is also being run by processor 84, then the sensor fusion thread 76 will be performed before the audio application. The SRE 14 can be implemented in any system that needs to be operated in a secure environment. For example, network servers or multiprocessors operating in a home environment. The multiprocessors in home appliances. Such as washer and dryers, home computers, home security systems, home heat ing systems, can be networked together and operate Java applications. The SRE 14 prevents these multiple processors and the Software that controls these processors from being corrupted by unauthorized software and also allows the appli cations on these different processors to operate as one inte grated system. The SRE 14 is a controlled trusted computing based that is not accessible by non-authorized application programmers and anyone in the general public. Therefore, the SRE 14 prevents hacking or unauthorized control and access to the processors in the vehicle. Task Controlled Applications Debugging is a problem with multiprocessor Systems. The task manager 58 allows the Java applications to be run in a lock-step mode to more effectively identify problems in the multiprocessor system 15. FIG. 5 shows a path 90 taken by a vehicle 92. In one application, the position of the vehicle 92 is sampled every second t, t t t etc. The position of the vehicle 92 is sampled by a GPS receiver in vehicle 92 that reads a longi tudinal and latitudinal position from a GPS satellite. The GPS receiver is controlled by the GPS thread 62 that receives the

thread 64 that may run on the same or a different processor in the vehicle 92. The sensor fusion thread 64 can perform any one of many different tasks based on the GPS data. For example, the sensor fusion thread 64 may update a map that is currently being displayed to the driver of vehicle 92 or gen erate a warning signal to the vehicle driver. For each sample period to the task manager 58 sends a request 94 to the GPS thread 62 to obtain GPS data. The task manager 58 uses a clock 96 as a reference for identifying each one second sample period. Each time a second passes accord ing to clock 96, the task manager 58 sends out the request 94 that wakes up the GPS thread 62 to go read the GPS data from the GPS satellite. Once the GPS data has been received, the

GPS thread 62 passes the UPS data 96 to the sensor fusion thread 64. The GPS thread 62 then goes back into an idle task manager 58. The task manager 58 can control when the GPS thread 62 is woken up. Instead of the GPS thread 62 being free running, the GPS thread 62 is operating according to a perceived time controlled by the task manager 58. The task manager 58 may send the activation request 94 to the GPS thread 62 once every second during normal sensor fusion operation. When the system is in a debug mode, however, the task manager 58 may only send one activation command 94. This allows the other operations performed by the system 89 to be monitored and determine how the single sampling of GPS data 96 propagates through system 89. The task manager 58 may also delay or disable task initiation to other threads, so that the processing
Thus, the task manager 58 controls when Java applications are activated effectively running the overall system 89 in a lock-step mode. The task manager 58 can control the initia tion of multiple tasks at the same time. This allows the task manager to control what parameters and operations are per formed and used by the different Java threads so that different states in the multiprocessor system 89 can be detected and monitored more effectively. One application for the task controlled applications is for accident reconstruction. The critical data manager 52 (FIG.3) may save different vehicle parameters from a vehicle that has been in an accident. For example, sensor data, brake data, speed data, etc. The task manager 58 can feed the saved data into the different Java applications in a lock-step mode to determine how each Java thread processes the saved data. This can then be used to identify any failures that may have occurred in the system 89. The system described above can use dedicated processor systems, micro controllers, programmable logic devices, or microprocessors that perform some or all of the communica tion operations. Some of the operations described above may be implemented in Software and other operations may be implemented in hardware. For the sake of convenience, the operations are described
