A Hardware/Software Cosimulator with RTOS Supports for Multiprocessor Embedded Systems

摘要

This paper presents a hardware/software cosimulator for multiprocessor embedded systems. Our cosimulator consists of multiple software simulators each of which simulates a set of application tasks together with an RTOS running on a processor, multiple hardware simulators and a cosimulation backplane. All of the simulators are executed concurrently with communication. Our cosimulator supports two types of communication; one is based on Remote Procedure Call (RPC), and the other is based on a shared memory on a host computer. Using the cosimulator, we successfully performed cosimulation of an MPEG encoder/decoder system with two processors and some peripheral circuits.
