Abstract

Methods, systems and computer readable storage medium for processing coherent data are provided. In an embodiment, a method for processing coherent data includes dividing the coherent data into two separate frames. Further, the method includes applying a same coherency number to the two separate frames and transmitting a signal including the two separate frames to a receiving module. The method also includes determining whether the two separate frames match based on the same coherency number. When the two separate frames match, the method outputs the two separate frames to downstream logic. The method may include adding the two separate frames to a buffer populated with a selected number of most recently received frames and, when the two separate frames do not match, identifying a selectedframe from the two separate frames and searching the buffer for a matching frame from the most recently received frames.

Description

technical field [0001] The present invention relates to methods and systems for processing coherent data. Background technique [0002] The Controller Area Network (CAN) bus is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host. It's a message-based protocol originally designed to save copper on multiple wires inside automobiles, but can be used in many other contexts as well. [0003] A modern car may have as many as seventy electronic control units (ECUs) for various subsystems. Usually the largest processor is the engine control unit. Others are used in transmissions, airbags, anti-lock braking systems / ABS, cruise control, power steering, audio systems, power windows, doors, mirror adjustment, batteries and charging systems for hybrid / electric vehicles, etc. Some of them form independent subsystems, but communication between other subsystems is essential. A controller or subsystem ...
