由于大型高速并行计算机系统的发展,对主存贮器的速度和容量的要求也越高。原在中小型计算机中,简单的存贮器控制已不适应大型机系统中对主存控制的需要。随着计算机系统结构,以中央处理机为中心发展到以主存贮器为中心来组织计算机,并业已采用LSI电路和半导体存贮器作主存,以分布式计算机概念来组织计算机系统的发展,存贮控制器,将用来作为协调和控制分散开的处理机的重要互连接口部件。特别是随着单片LSI微处理机,多处理机系统结构的发展,使存控部件将成为一个互连子系统,来 Due to the development of large high-speed parallel computer systems, the requirements for the speed and capacity of main memory are also higher. In small and medium-sized computers, simple memory control has become inadequate for mainframe control in mainframe systems. With the structure of a computer system, the central processing unit has been developed as a center for organizing computers with a main memory as the center. The LSI circuit and the semiconductor memory have been adopted as the main memory, and the concept of a distributed computer has been used to organize the development of a computer system , A storage controller that will be used as an important interconnect interface component for coordinating and controlling distributed processors. Especially with the monolithic LSI microprocessor, multiprocessor system structure, the control component will become an interconnection subsystem, to
