3. 발명의 해결방법의 요지3. Summary of Solution to Invention
알아이에스씨 구조를 갖는 장치의 듀얼 리드포트 레지스터 화일 뱅크회로에 있어서, 고유의 번호를 갖는 다수의 옵셋영역으로 이루어진 뱅크를 다수 구비하며, 소정의 어드레스에 라이트백 데이타를 저장하고 그 저장된 데이타를 제1포트를 통해 출력하는 주메모리와, 상기 주메모리와 동일 체계로 고유의 번호를 갖는 다수의 옵셋영역으로 이루어진 뱅크를 하나 구비하며, 소정의 어드레스에 상기 라이트백 데이타를 저장하고 그 저장된 데이타를 제2포트를 통해 출력하는 부메모리와, 상기 제1포트를 통해 소정의 데이타가 출력되면 해당 옵셋영역의 데이타 유효여부를 나타내는 유효비트를 외부로부터 입력되는 뱅크변환신호의 상태에 따라 셋 혹은 리셋하고, 상기 뱅크변환신호와 상기 라이트 뱅크 어드레스를 조합하여 파이프라인 스톨신호를 발생하는 유효 비트 판단부와, 소정의 제어를 받아 라이트 뱅크 어드레스와 제1포트 리드 어드레스중 하나를 상기 주메모리에 선택적으로 제공하는 제1선택수단과, 소정의 제어를 받아 제2포트 리드 어드레스와 상기 라이트 뱅크 어드레스중 하나를 상기 부메모리에 선택적으로 제공하는 제2선택수단과, 상기 유효비트의 셋 여부에 따라 상기 라이트백 데이타 혹은 상기 주 메모리의 제1포트에서 출력되는 데이타를 상기 부메모리에 선택적으로 전달하는 제3선택수단으로 구성됨을 특징으로 한다.A dual read port register file bank circuit of a device having an RS structure, comprising a plurality of banks having a plurality of offset areas having a unique number, storing writeback data at a predetermined address, and removing the stored data. A main memory output through one port, and a bank comprising a plurality of offset areas having a unique number in the same scheme as the main memory, and storing the writeback data at a predetermined address and removing the stored data. When a predetermined data is output through the first port and the sub memory output through the two ports, and a valid bit indicating whether or not the data of the offset area is valid, the set memory is set or reset according to the state of the bank conversion signal input from the outside. A pipeline stall signal is generated by combining the bank conversion signal and the write bank address. A valid bit determination unit configured to selectively provide one of the write bank address and the first port read address to the main memory under predetermined control, and the second port read address and the predetermined control under the predetermined control. Second selection means for selectively providing one of write bank addresses to the sub-memory, and selectively outputting the write back data or data output from the first port of the main memory to the sub-memory according to whether the valid bit is set. Characterized in that the third selection means for transmitting to.
