Abstract: This application discloses tools and mechanisms to convert a program from a sequentially-executable format into a parallel-executable format, and then modify the program in the parallel-executable format to either allow compilation for parallel execution or to speed-up the parallel execution by an accelerated processing unit. The tools and mechanisms can identify various features of the program, such as recursive calls, search loops, inline function calls, uncompressed data structures, memory utilization, and inter-dependent kernel instances. The tools and mechanisms can modify the program to replace or otherwise augment the identified features, which can allow the modified program to be compiled for parallel execution, or speed-up the parallel execution by an accelerated processing unit.

Abstract: This application discloses a controller area network node including a controller and a transceiver. The transceiver includes security circuitry to perform various security checks on messages the controller area network node intends to have transmitted over a shared bus in a controller area network. The security circuitry can determine whether the messages conform to the rules associated with a design and a traffic scheduling of the controller area network. Some of those rules include that the controller area network node transmit messages with identifiers that were assigned to the controller area network node, or transmit messages with a specified timing. When the security circuitry identifies one of the messages fails to conform to the rules for the controller area network, the security circuitry can initiate a security action, such as refusing or delaying transmission of the messages or reporting the rules violation to the controller.

Abstract: The present invention relates to a method of communicating data between at least two units (1) on a serial bus (2) in a car, wherein the units 11) have independent clocks, the data being transmitted as a sequence (3) of frames (4), each frame including an identifier field (9) and a data field (10). In order to ensure an always reliable and synchronized communication of data on a serial bus with different types of units (clocks) where randomly distributed periods of idle time may occur on the bus it is suggested that prior to any sequence (3) of frames (4), a signal pattern (7) is transmitted on the bus (2), so as to set the bus to a definite state for a predetermined period of time.
