| Popis: | This paper proposes general software optimization techniques for embedded systems based on processors, which mainly include general optimization methods in high language and software and hardware co-optimization in assembly language. Then these techniques are applied to optimize our MP3 decoder, which is based on RISC32, a RISC core compatible with MIPSI instruction set. The last optimization decoder requires 48 MIPS and 49 Kbytes memory space to decode 128 Kbps, 44.1 KHz joint stereo MP3 in real time with CPI 1.15, and we have achieved performance increase of 46.7% and memory space decrease of 38.8% over the original decoding software. |
