MICROPROCESSORS aims to present to the readers, the evolution of Microprocessors. In the first part the working of Intel 8086 processor along with all the support chips required to design an 8086 based system, the timing diagram of the different Bus Cycles and the Multiprogramming and Multiprocessing features of Intel 8086 have been discussed. The second part covers Intel 80386 processor in Protected Mode, wherein the segmentation, paging and Multitasking features alongwith real to protected mode transition and vice-versa have also been discussed. The book includes two chapters on design of an Intel 8086 processor based system along with inputs to write the Monitor program and Design of an 8 bit two stage pipelined processor and its implementation on XILINX VIRTEX-5 FPGA.
