Research and implementation of virtual processor X86

The application range of traditional ISA microprocessors is seriously limited due to its internal limited logic resources and external fixed-pin package.For example 8086,the abundant logic resources of FPGA can be fully used to implement the various components of the traditional microprocessors and their configurable IO pins can be used to reduce the degree of the complexity of the hardware design.As for the upper software engineers,the programming operation is in accord with standard MCU to build the system in this way.On the other hand,the largest extent freedom of hardwares can be obtained by using the configurable IO pins freely.Owing to adopting the on-chip bus,the system can be customized in terms of actual needs,such as the need to increase the variety of peripherals so as to achieve the requirements that cannot be acquired by the standard microprocessors.The result of verification in board level indicates the set objective has been achieved,that is to say that the system has better compatibility with the standard MCU 8086 and runs stable.
