摘要
精简指令系统计算机 (简称RISC)的主要特点是CPU的指令集大大简化 ,用简单的指令来提高机器的性能 ,特别是提高CPU执行程序的速度。介绍了RISC技术的起源和它所采用的一些基本技术 。
The Reduced Instruction Set Computer(RISC,for short)has the main characteristic of the greatly simplified instruction set in CPU.The functions of computer,especially the program performing speed of CPU,are enhanced by using the simple instructions.The origin and basic techniques of RISC are introduced,and the advantages and disadvantages of RISC technology used in computer system as well.The developing direction of RISC technology is pointed out.
