Abstract

Recently multiple process communicate together. They share resource and information for cooperation in complicated programming environment. Kernel provides IPC (Inter -Process Communication) for communication with each other process. Shared Memory is a technique that many processes can access to identical memory area in the Linux environment. In this paper, we propose a performance improvement method of shared memory in the dual-core embedded linux system which is consist of different core and different operating system. We construct the MPC2530F (ARM926F+ARM946E) linux system and measure the performance therein. We attempt a performance enhancement in each CPU for each process which uses a shared memory.
