Abstract

본 발명은 ROM의 억세스 시간 제어 방법에 관해 게시한다. 종래에는 ROM의 어게스 시간에 따라 ROM의 데이터 독출시간이 결정되었으나 본 발명에 따르면 ㅍ의 억세스 시간에 상관없이 ROM의 데이터 독출시간을 일정하게 할 수 있다.The present invention discloses a method for controlling access time of a ROM. Conventionally, although the data read time of the ROM has been determined according to the access time of the ROM, the data read time of the ROM can be made constant regardless of the access time of the ROM.

Description

Claims (1)

카운터와 레지스터의 값을 비교하는 비교기와 상기 비교기로부터 신호를 받아 ROM의 데이터를 독출하는 플립플롭을 제어하는 펄스발생기를 갖는 퍼스널 컴퓨터의 그래픽제어장치에 있어서, 상기 레지스터에 ROM의 데이터 독출시 억세스 시간에 따른 적절한 값을 설정해 놓는 것을 특징으로 하는 ROM의 억세스 시간 제어 방법.A graphic control apparatus of a personal computer having a comparator for comparing a counter and a register value, and a pulse generator for controlling a flip-flop that receives a signal from the comparator and reads data from the ROM, wherein the graphic controller of the personal computer has access when the ROM data is read into the register. ROM access time control method characterized in that the appropriate value set over time. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
