Abstract

The architecture of ARM7 processor is introduced . We realize optimization of MPEG -4 decoder with arithmetic , language and ARM optimization method, according to the features of decorder and chip architecture. The results indicate that we have successfully realized the optimization of ARM7 video decoder,it also reduces lots of data processing time,and can satisfy the request of low resolution,low frame-rate under the conditions of real-time decoding.
