Abstract
본 발명은 하드 디스크 드라이버 등의 기억장치에 버퍼로 사용되는 램의 어드레스 공간을 여러개로 구분함으로써, 버퍼의 사용효율을 향상시키는 버퍼램의 고정된 세그먼테이션의 구현장치에 관한 것으로서, 그 구성은 초기에는 상기 마이크로프로세서의 인에이블 신호에 의해 상기 마이크로프로세서의 데이터를 출력하고, 이후에는 선택된 램의 어드레스 번지를 선택하여 출력하는 멀티플렉서; 상기 멀티플렉서로부터 초기에 출력되는 마이크로프로세서의 데이터를 싣고, 이후에는 램의 어드레스 번지에 싣는 어드레스 포인터; 세그먼트 크기를 결정하는 세그먼트 크기 레지스터; 상기 마이크로프로세서의 라이트 신호와 다음의 클럭신호를 조합하여 출력하는 오아 게이트; 및 상기 오아게이트에서 출력되는 다음의 클럭이 “1”이 될때 마다 상기 어드레스 포인터로부터 출력되는 현재의 어드레스번지 보다 하나 큰 어드레스 번지를 지정하는 신호와 상기 세그먼트 크기 레지스터의 출력 신호에 의해 결정된 어드레스번지를 상기 멀티플렉서로 출력하는 세그먼트 어드레스 가산기를 포함한다.The present invention relates to an apparatus for realizing a fixed segmentation of a buffer RAM for improving buffer utilization efficiency by dividing a plurality of address spaces of a RAM used as a buffer in a storage device such as a hard disk driver, A multiplexer for outputting the data of the microprocessor according to an enable signal of the microprocessor, and thereafter selecting and outputting an address address of a selected RAM; An address pointer for loading data of a microprocessor initially output from the multiplexer and then putting the data in an address address of the RAM; A segment size register for determining a segment size; An o gate for outputting a combination of a write signal of the microprocessor and a next clock signal; And a signal designating an address address which is one larger than the current address address output from the address pointer every time the next clock outputted from the gate is " 1 ", and an address address determined by the output signal of the segment size register And a segment address adder for outputting to the multiplexer.
따라서, 상술한 바와 같이 본 발명에 따른 버퍼램의 세그먼테이션의 구현장치는 램의 어드레스 공간을 여러개로 구분함으로써, 버퍼의 사용효율을 증가시키며, 칩으로 구현시 칩의 크기가 작게 되는 효과를 갖는다.Therefore, as described above, the apparatus for realizing the segmentation of the buffer RAM according to the present invention divides the address space of the RAM into several parts, thereby increasing the buffer utilization efficiency and reducing the size of the chip when the chip is implemented.
