3. 발명의 해결방법의 요지3. Summary of Solution to Invention
지령완충 실행장치와, 제어장치와, 데이타 레지스터를 이용하여 기억장치에 기억된 테이블 룩업데이타를 데이타 레지스터에 출력하는 테이블 룩업방법에 있어서, 제1타이밍주기에 있어서, 상기 지령완충 실행장치에 의해 미리 기억된 테이블 룩업지령을 실행하여 테이블 룩업신호를 발생시켜서 출력한 후, 상기 제어장치에 의해 이 테이블 룩업신호에 따라서, 상기 기억장치에 기억된 서브코멘트를 상기 지령완층 실행장치에 출력하는 단계(a)와, 제2타이밍주기에 있어서, 상기 제어장치에 의해 사용금지신호가 발생하여 상기 지령완층 실행장치에 있어서의 상기 서브코멘드를 래치한 후, 상기 제어장치에 서입지령이 발생하여 이것을 상기 지령완층 실행장치에 출력시키는 것에 의해, 상기 지령완충 실행장치에 서입신호가 발생하여 상기 테이블 데이타를 상기 데이타 레지스터로 출력하는 단계 (b)를 구비함을 특징으로 한다.A table lookup method for outputting a table lookup data stored in a storage device using a command buffer execution device, a control device, and a data register to a data register, wherein the command buffer execution device is used in advance in a first timing period. Executing a stored table lookup command to generate and output a table lookup signal, and then outputting, by the controller, the subcomment stored in the storage device to the command completion layer execution device in accordance with the table lookup signal (a) ), And in the second timing period, a prohibition signal is generated by the control device to latch the sub-command in the command complete execution device, and then a write command is generated to the control device to generate the command. By outputting to the slow floor execution apparatus, a write signal is generated in the said command buffer execution apparatus, and the said table data is performed. And the characterized in that a step (b) to output to said data register.
