EISC

EISC(Extendable Instruction Set Compter,可擴展指令集計算機)是為了減少程式大小和記憶體訪問頻率而專門設計的指令集。它還具有能擴充立即數和錯值的擴充指令。總之，它集CISC(Complex Instruction Set Computer複雜指令集計算機) 和 RISC(Reduced Instruction Set Computer精簡指令集計算機)的優點於一身。

基本介紹

• 中文名：EISC
• 外文名：Extendable Instruction Set Computer
• 優點：擴充立即數和錯值的擴充指令
• 目的：為了減少程式大小和記憶體訪問頻率

EISC (Extendable Instruction Set Computer) is the specially designed instruction set that can reduce the program size and the frequency of the memory access efficiently. And it is also able to expand the values such as immediate or displacement value using expanded instructions. As a result, it has the advantages of both CISC and RISC architectures.
