摘　　要：嵌入式系统是计算机新的应用领域。在嵌入式应用中，ＲＩＳＣ处理器已经完全取代了ＣＩＳＣ处理器。目前ＤＳＰ产品也开始在嵌入式应用中得到了使用。本文对比了ＲＩＳＣ和ＤＳＰ的结构特点，并对它们在嵌入式应用中的方案进行了比较，给出了择优标准．Embedded systems are new fields of computer applications. RISC prcocessors have already kicked CISCout of more than a few embedded applications. Now,DSPs are iring to prove that they can be just as usefulin embedded applications. In this paper, we contrastthe architectural features of RICSs with that of DSPs,compare their schemes in embedded applications, andgive the choice standards.
