Design Automation of Sequential Machines

순차제어기의 자동설계에 관한 연구

This paper is concerned with the design automation of the sequential machines. The operations of sequential machine can be diveded into two types such as synchronous and asynchronous sequential machine and their realization is treated in separate mode. But, in order to integrate logic circuits in high volume, mixed mode sequential machine uses common circuitry that consists of gates and flip-flops. Proposed sequential machine can be designed by several method, which are hard-wired implementation, firmware realization by PLA and ROM. And then onr example shows the differnces among three design mothods. Finally, computer algorithm(called MINIPLA) is discussed for various application of mixed-mode sequential machine.
