精简指令系统计算机(RISC)的研究与实现

The Research and the Implementation of RISC

随着计算机应用领域的不断扩大,对计算机技术要求也越来越高。如何增强计算机系统的功能,简化编译器的工作量,提高计算机的运行速度和效率,已是计算机工作者的重要研究课题。通过对计算机系统结构的合理设计,可以使软、硬件功能得到合理的分配。而硬件设计的核心便是处理机设计,设计处理机的基本任务之一就是要缩短解释指令的时间。RISC(精简指令系统计算机)技术能够减少执行指令的平均周期数,从而减少指令执行时间,提高计算机系统的效率。

The increasing applications of computers require technology development. It is important to improve the functions and efficiency of computer system as well as reduce the work flow of compiler. By rational design of computer system structure, the best distribution of soft- ware and hardware fmlctiom can be realized. The processor design is the core of hardware design. One of the basic tasks of processor design is to shorten the time to explain the directive. RISC can reduce the average number of cycles to execute instructiom, thereby effectively im- prove the instruction execution speed.
