Overview
Automotive networks increase their importunateness in complex automotive electronic control units. CAN (Controller Area Network) has already been adopted as the defector standard in body, power train and chassis systems. It has been enabled the efficient communication between those ECU's, and achieves advanced system control. However, consumer demand in comfort system and OEM,s safety system requirement is increase its demand in an automotive network system that is demanding next generation network. And, thus , an industrial consortium FlexRay has formed in 1999, and develops new standard FlexRay with alliances, FlexRay is a high-speed and highly reliable network ,widely getting attention from European and Japnese OEMs and suppliers.

FUJITSU joined FlexRay Consortium in 2002. In November 2004, FUJITSU has licensed the FlexRay IP from Bosch. In February 2005, FUJITSU introduced a starter kit mounting FlexRay IP on a FPGA; many customers have already evaluated FlexRay through this kit. FlexRay ASSP, MB88121A featuring protocol version 2.1 in November 2005 which will be followed by MB88121B in 2Q 2006, providing fully tested ERAY core from BOSCH.
Fig. 1 presents typical schematic of the in-vehicle network. FlexRay is a network that realizes high-speed and high reliability data communication with transmission speed up to 10Mbps.
