Abstract
본 발명은 디스크의 데이타를 엑세스(ACCESS)할 경우에 데이타의 크기를 확장 전송하여 시스템 전체의 성능을 향상시킬 수 있도록 하는 것으로서 종래에는 1회 데이타의 최대 전송량이 12K바이트로 규정되어 많은 양의 데이타를 전송할 경우에 매우 비능률적일 뿐만 아니라 데이타 전송시간이 많이 소요되었다.The present invention is to improve the performance of the entire system by extending the size of the data when accessing the data on the disk (ACCESS) in the past, the maximum transfer amount of data once is defined as 12K bytes, a large amount of data Not only is it very inefficient when transmitting the data, but it also takes a lot of data transfer time.
본 발명은 디스크 드라이브 콘트롤러의 데이타 버퍼모듈의 메모리 용량을 최대로 지원이 가능한 32K바이트로 확장하고, 펌웨어의 파라메타인 DSKHDR1의 변수값과, 입출력 드라이버에서 데이타의 크기를 결정하는 파라메타인 MAXIPC??르 28K바이트로 확장하여 1회 전송되는 데이타의 크기를 28K바이트로 확장함으로써 1회에 많은 데이타를 전송함은 물론 데이타의 전송속도를 향상시킬 수 있다.The present invention extends the memory capacity of the data buffer module of the disk drive controller to 32K bytes that can support the maximum, and the variable MAXIPC which determines the size of data in the I / O driver and the variable value of the firmware parameter DSKHDR1. By extending the size of data transmitted once by expanding it to 28K bytes to 28K bytes, it is possible to transmit a lot of data at once and improve the data transmission speed.
