AUTOSAR 1 1, 2 2 2 AUTOSAR AUTOSAR 3 2 2 41% 29% An Extension of AUTOSAR Communication Layers for Multicore Systems Toshiyuki Ichiba, 1 Hiroaki Takada, 1, 2 Shinya Honda 2 and Ryo Kurachi 2 AUTOSAR, a software platform for automotive systems, assumes only an ECU with a single core processor, and does not consider an ECU with a multicore processor. It is necessary that a communication on a multicore processor because ECUs communicate each other for cooperative control. There are three communication types: a inside core, a inter core, and a outside chip communications. This paper proposes two methods for outside chip communication: a lock method and a server method. An existing communication middleware is extended as the two methods. Compared to a single core processor, the results of extended middleware show that transmission time overheads of the lock method and the server method are 41% and 29%, respectively. 1.
