Abstract
듀얼포트 메모리로 사용키 위한 램(RAM)(201)의 메모리 제어방법에 있어서, 기준클럭(8MHZ)을 2차로 분주하여 제1, 2클럭(2MHZ, 4MHZ)을 발생에 따라 상기 램 (201)의 억세스되는 제1, 2측에서 데이타를 양방향을 버퍼링하고, 상기 분주되어 발생되는 4MHZ클럭에 의해 상기 버퍼링된 출력을 선택하여 램(RAM)(201)에 제공하In the memory control method of the RAM (201) for use as a dual-port memory, the reference clock (8MHZ) is divided into two by the first and second clock (2MHZ, 4MHZ) in accordance with the generation of the RAM (201) Buffer the data at both sides of the first and second sides of the first and second sides, and select and provide the buffered output to the RAM 201 by the 4MHZ clock generated.
며, 상기 제1, 2측 프로세서로부터 제어신호를 받아 상기 램(201)의 램의 인에이블(RME), 라이트/출력인에이블 신호(RME, WEB, OEB)를 발생하고, 상기 포트선택단(POR)의 신호와 제1, 2측 인터럽트 리드/클리어신호단(L/RINTWR, L/RINTCLR)의 신호를 받아 제1, 2측 인터럽트신호(L/R INT)를 발생하도록 이루어진다.In response to the control signal from the first and second processor, the RAM enable (RME) and write / output enable signals (RME, WEB, OEB) of the RAM 201 are generated, and the port selection terminal ( POR) and the first and second interrupt read / clear signal terminals L / RINTWR and L / RINTCLR to receive the first and second interrupt signals L / R INT.
