现在用ARM来解码MP3的产品也有很多，看看对大家应该有些帮助。

【简　介】:
We have implemented the MPEG 1/2 audio Layer-III
decoding algorithm using ARM7 and ARM9 based
systems. Optimizations are conducted in the algorithm, Cprogram,
and assembly program levels. The assembly
program level optimization that employs the block data
transfer instructions intensively is very effective for
reducing the number of memory accesses. The
performance effects of memory architectures, such as the
number of internal buses, cache size, and cache schemes
are measured both for ARM7 and ARM9 systems. The
overhead of clock cycles due to external DRAM accesses
is shown about 40% for a typical ARM7 based system,
and 19% to 1.6% for typical ARM9 based systems.
