计算机由中央处理设备(包括主存贮器和运控设备)和外围设备(包括输入、输出设备)组成。过去,一般都采用磁芯作主存贮器,这需要几十万到几千万个磁芯。为了处理大量的数据需要增大存贮容量;另一方面,用运控设备进行数据运算和控制时,如果不能高速工作,就不能提高计算机的处理能力。由于半导体器件具有高速性能、小型化、可靠性高、功耗小,首先在运控设备中得到了应用。由于主存贮器使用磁心,缩小
Computer by the central processing equipment (including main memory and control equipment) and peripherals (including input and output devices). In the past, magnetic cores were generally used as main memory, which required hundreds of thousands to tens of millions of magnetic cores. In order to handle a large amount of data, the storage capacity needs to be increased. On the other hand, when the data operation and control are performed by the operation and control equipment, if the computer can not work at high speed, the processing capacity of the computer can not be improved. As the semiconductor devices with high-speed performance, miniaturization, high reliability, low power consumption, the first operation and control equipment has been applied. As the main memory using the core, reduced
