An efficient implementation of protocol operation control unit of FlexRay communication controller

In an automobile industry, more sophisticated functions are integrated to vehicles. These functions are controlled and monitored by different Electronic Control Units (ECU). FlexRay protocol is a flexible, high-speed, deterministic, error-tolerant and reliable communication technology. It is designed to meet growing safety related challenges associated with the automobile industry. FlexRay Communication Controller is responsible for implementing the protocol aspects of the FlexRay communication system. It performs all communication tasks such as reception and transmission of messages in a cluster without interaction with the host CPU. This paper deals with the FPGA implementation of the Protocol Operation Controller (POC) unit of FlexRay Communication Controller using VHDL language.
