UNIT III 8086 MICROPROCESSOR INTERFACING 3.1 Introduction This unit explains how to design and implement an 8086 based microcomputer system. To design an 8086 based system‚ it is necessary to know how to interface the 8086 microprocessor with memory and input and output devices. Due to the mismatch in the speed between the microprocessor and other devices‚ a set of latches and buffers are required to interface the microprocessor with other devices. In this unit‚ you will learn about the way in

Evolution of Microprocessor It is interesting to note that the microprocessor had existed for only 10 years prior to the creation of the PC! Intel invented the microprocessor in 1971; the PC was created by IBM in 1981. Now more than 20 years later‚ we are still using systems based more or less on the design of that first PC. The processors powering our PCs today are still backward compatible in many ways with the 8088 that IBM selected for the first PC in 1981. November 15‚ 2001 marked the 30th anniversary

The 6800 * After seeing the success of Intel ’s 8-bit 8008 microprocessor‚ Motorola introduced its first 8-bit microprocessor‚ the 6800‚ in 1974. The 6800 became more prevalent due in part to the system oriented support hardware that Motorola introduced with the 6800. The 6800 was competing in the market with the Intel 8080. The 6800 was used in some early home computer kits‚ the Tektronix 4051 Graphics Computer System and in a microprocessor trainer sold by Heathkit. The 6809 * Around 1977
