许多微型计算机应用需要先进的CPU性能,使其不仅适于16位μρ,并可直接与现有的8位系统兼容。英特尔8088CPU满足了这种需要。通过将工业标准的8085A的8位硬件接口与8086的内部16位结构相结合,8088CPU把16位内部结构性能应用到8位系统。结果给人留下深刻的印象:即更快速的算术运算和逻辑运算,更大的数据处理容量以及大大地改进存储器和1/0寻址技术。该结构允许8088用8位或16位数据有效地工作并用串和块两种形式处理数据。用
Many microcomputer applications require advanced CPU performance, making them suitable not only for 16-bit μρ, but also for direct compatibility with existing 8-bit systems. Intel 8088CPU to meet this need. By combining the industry standard 8085A’s 8-bit hardware interface with the 8086’s internal 16-bit architecture, the 8088CPU applies 16-bit internal structure performance to 8-bit systems. The result is impressive: faster arithmetic and logic operations, greater data processing capacity, and dramatically improved memory and I / O addressing. This structure allows the 8088 to work efficiently with 8-bit or 16-bit data and process the data in both forms of blocks and blocks. use
