Abstract

Embedded system simulation has become very time expensive in recent times due to the increasing complexity of system models. Efficient and fast simulations play a crucial role in the embedded system development. The current SpecC simulator uses the Posix thread library, Quickthreads or Win32 libraries to achieve multithreading. This report proposes the usage of a custom thread library based on native linux primitives to achieve the same functionalities. Our proposed custom thread library named Litethreads is developed with the goal of having the advantages of both user-level threads, like Quick threads, and kernel-level threads, like Pthreads. Preliminary simulation results indicate significant improvement in simulation time for some design samples including an mp3 decoder. Contents
