Abstract

본 발명은 큐(Queue)를 이용한 점프 타입 명령 처리방법에 관한 것으로 종래에는 명령 코드를 저장하여 점프 타입의 명령 코드를 판별하면 기존에 큐(Queue)에 저장된 명령코드를 클리어한 후 점프 타입의 명령 코드에 따른 어드레스부터 명령코드를 저장하여 명령을 수행함으로 명령 수행간 지연시간이 발생되어 프로세서의 성능을 저하시키는 문제점이 있었다.The present invention relates to a jump type command processing method using a queue. Conventionally, when a command code is stored and a jump type command code is determined, the jump type command is cleared after the command code stored in the queue is cleared. There is a problem that the performance of the processor is degraded because the delay time between the execution of the instructions is generated by storing the instruction codes from the address according to the codes.

이러한 점을 감안하여 본 발명은 큐(Queue)에 저장되는 명령코드를 점검함에 따라 점프(JUMP)또는 콜(CALL)타입의 명령코드를 점검함에 따라 점프(JUMP)또는 콜(CALL)타입의 명령코드를 검출하면 이 점프타입의 명령코드 이후의 명령코드를 클리어한 후 점프타입의 명령코드에 따른 어드레스부터 명령코드를 순차 저장하게 된다. 따라서 명령 수행간 지연시간이 제기되어 프로세서의 성능을 향상시킬수 있다.In view of this point, the present invention checks the command code stored in the queue and checks the jump code of the jump or call type. When the code is detected, the instruction code following the instruction code of this jump type is cleared, and the instruction code is sequentially stored from the address corresponding to the instruction code of the jump type. Therefore, the delay time between the execution of the instruction is raised can improve the performance of the processor.

Claims

Check the command codes stored in the queue sequentially to determine whether they are jump (JJUMP) or call (CALLl) type command codes. The second step of repeating the first step and the jump or call type command code in the first step are cleared, and the instruction code following the jump type command code is cleared after the operation is performed. And a third step of sequentially storing the command code from the address and repeating the first step.

The jump using a queue queue according to claim 1, wherein the jump type command code is detected in the third step and the address generator 13 is controlled to generate an address Addr according to the command code. How type commands are handled.
