Abstract: This paper designs a state machine system for the multimedia player based on ARM platform and takes a series of measures to optimize the system performance. It implements high performance calculation like soft-decoding on a restricted general-purpose processor and realizes an embedded system with high performance, low power and low cost.

Key words: Embedded system, ARM processor, State machine, Performance optimization

摘要: 基于ARM平台设计了一个状态机控制的多媒体播放器系统,并进行了相应的性能优化,从而在资源受限的通用处理器上实现了软解码的高性能计算,完成了一个高性能、低功耗、低成本的嵌入式系统。
