(二)寄存器和移位寄存器寄存器是计算机的一个重要部件,用于暂存参加运算的数、运算结果、指令等,为了寄存信息,它必然是由有记忆功能的触发器所组成,此外还要有一些接收数据的控翩门,使寄存器各触发器在同一个接收命令作用下接收信息。在计算机中常常要求寄存器有“移位”功能。例如,进行乘法运算时要将部分积右移,除法运算时则要把余数左移。将并行传送的数转换成串行传送的数
(B) of the register and the shift register Register is an important part of the computer, used to temporarily store the number of operations, computing results, instructions, etc., in order to register information, it must be composed of memory-based triggers, in addition There should be some receiving data control Pina gate, so that the register receives the trigger under the same command to receive information. Registers are often required to be “shifted” in the computer. For example, to multiply the part of product to the right shift, the division will have to move the remainder left. The number of parallel transfers is converted to the number of serial transfers
