一、引言 美国IBM公司于1983年9月份推出了4300系列计算机的两个新机种——4361处理机和4381处理机。这两个新机种引起了世界各地计算机用户的热切关注,大批订货单纷纷而来,形成了前所未有的供不应求的局面。 4361处理机是4331处理机的改进型。4331 机只需化几个小时,就可在用户现场升级成4361处理机。4361机的工艺结构基本上与4331机相同,只是在部分元器件性能上和逻辑组织上有所 I. Introduction IBM Corporation in the United States in September 1983 launched two new models of 4300 series computers - 4361 processors and 4381 processors. These two new models have aroused the fervent concern of computer users all over the world. A large number of order forms have come in one after another, creating an unprecedented supply shortage situation. The 4361 processor is an improved version of the 4331 processor. 4331 machine just a few hours, you can upgrade to 4361 processor at the user site. 4361 machine structure is basically the same with the 4331 machine, but part of the performance of components and logical organization
