A study on an implementation of the custom control circuit for optimizing the interface of peripheral devices to general-purpose controllers

범용 제어기의 주변 소자 접속을 최적화하기 위한 전용 제어 회로의 구현 연구

This paper deals with the design scheme of the custom control circuit for optimizing the interface of peripheral devices to general-purpose controllers for the high speed digital system. When the various peripheral devices such as memory, I/O devices and buffers which operate at low speed are interfaced to the microprocessor which operates at high speed, inserting the proper wait state to the processor is required. The proposed scheme designed with random logic may be applied to the high performance graphic system like the X-terminal. This circuit provides the flexibility and system independancy for the optimum digital system design.
