INTEL 8087数值数据处理器是一种辅助处理器芯片,如将其加配在以INTEL8086或8088为CPU的微机上,就可使系统增添浮点运算能力,数值处理速度将提高10～100倍,大大增强了原机对数值数据的处理能力。本文介绍在最大方式或最小方式下工作的86/88微机上,直接加配8087的方法,而对原有的硬件和布线不作任何改动,本文还将介绍8087函数子程序库(如三角函数等)的移植和分析。目前,我们已在SDK-86单板机上加配了8087,并配上了8087子程
INTEL 8087 numerical data processor is a kind of auxiliary processor chip, such as adding it to the computer with INTEL8086 or 8088 for the CPU, you can increase the system floating-point computing power, numerical processing speed will increase 10 to 100 times, greatly Enhance the original machine on the numerical data processing capabilities. This article describes the way in the maximum mode or minimum 86/88 microcomputer, the method of adding 8087 directly, and the original hardware and wiring without any changes, this article will also introduce 8087 function subroutine library (such as trigonometric functions, etc.) Transplant and analysis. Currently, we have added 8087 to the SDK-86 SBC with 8087 subroutines
