Emulation of computer networks by microprogrammable microcomputers
David Avery Cohen, Ming T. Liu · 1974
The advent of low cost, sophisticated, microprogrammable, LSI microprocessors has renewed interest in multiple-computer systems. This paper suggests a method of implementing microprogrammable microcomputer systems as a sophisticated tool (emulators) for decreasing the economic risk involved in development of large computer networks. Two levels of emulation are proposed for different network configurations. At the first level each microprocessor emulates one of the large computers in the real network. At the second level of emulation, an additional microprocessor emulates the front-end processor associated with each large computer. The Intel 8080 microprocessors are selected for implementing the systems described.
