一、概述随着近代超大规模集成电路的高度发展,自七十年起国外一些主要芯片生产厂家在原8位微处理器的基础上朝两个方向发展自己的产品。其一是发展高性能的16位和32位微处理器及其系列化产品;其二是在单独一块芯片上集成一套完整的微处理机所应有
I. Overview With the rapid development of modern VLSI circuits, some major chip manufacturers abroad have been developing their products in both directions based on the original 8-bit microprocessors since the 1970s. One is the development of high-performance 16-bit and 32-bit microprocessors and their serialization products; the second is the integration of a complete set of microprocessors on a single chip
