KSJ－2850机宏指令处理方案的设计与实现

DESIGN AND IMPLEMENTATION FOR THE MACROINSTRUCTION PROCESSING SCHEME OF KSJ-2850 COMPUTER

ＫＳＪ－２８５０是我国第一台自主研制ＣＰＵ的、在体系结构级与ＶＡＸ系列兼容的计算机。它在系统设计上的重要技术成果之一是实现了高效率的宏指令处理方案。这一方案的实施对提高ＣＰＵ速度起到了重要作用。本文即介绍它的设计思想和实现方法。

KSJ-2850 superminicomputer, with its CPU firstly developed on our own at home, is fully compatible with VAX family at architecture level.One of the significant technical achievements in system design lays on the implementation of efficient macroinstruction processing scheme.The effection of the scheme plays an important role on increasing CPU speed. The paper gives the implementation method as well as design idea.
