Source code optimization for embedded processing software of tactical communication system

This paper presents general source code optimization techniques to optimize software performance and energy in embedded systems. Source code optimizations can be categorized into three levels: algorithmic, source code-level. Then these techniques are applied to optimize our KVMF processing software, which is a message encoder-decoder for tactical communication equipped on weapon systems in Korean Army. The optimized software achieved performance increase of 11.4% at most and memory space decrease of 61% over the original software.
