By studying on multimedia processing instruction sets attached to modern microprocessors, PowerPC microprocessors were chosen as main develop platform in this thsis, which were widely applied in the fieled of communications and image processing.

• 本论文通过研究现代微处理器上提供的多媒体指令集，选择在通信和图像处理领域被广泛应用的PowerPC微处理器作为开发平台，利用Motorola公司为PowerPC G4系列以后的微处理器开发的AltiVec多媒体指令集，对JasPer软件进行了优化。
