Abstract

본 발명은 실시간 처리 유닛(RPU)(Realtime Processor Unit)과 SHA(SCSI Host Adapter)의 인터페이스 제어방법에 관한 것으로 특히, 미니컴퓨터 기종의 SCSI드라이브(하드디스크 드라이브 및 카트리지 드라이브)를 사용하는데 있어 그 인터페이스를 구현하는데 적합한 인터페이스 제업아법에 관한 것으로 종래의 RPU와 입출력 채널과의 인터페이스 프로토콜(PROTOCOL)은S HA에 적용할 수 없는 제약을 해소하기 위한 것이다.The present invention relates to a method for controlling an interface between a real time processor unit (RPU) and a SCSI host adapter (SHA). In particular, the interface of a minicomputer-type SCSI drive (hard disk drive and cartridge drive) is used. The present invention relates to an interface manufacturing method suitable for implementing a conventional interface protocol (PROTOCOL) between an RPU and an input / output channel to solve a limitation that is not applicable to S HA.

본 발명은 MFB버스를 통해 RPU, 메모리등과 연결되어 사용하는 SCSI제어기 (Controller)인 SHA를 통해 SCSI 드라이들을 구동함에 있어 SHA 명령워드를 큐 인덱스 (Queue Index)와 명령 큐를 사용하여 전송하고, SHA어텐션 워드를 어텐션 큐 인덱스와 어텐션 큐를 사용하여 수신하므로서 각각의 유닛트간의 통신장애를 극복하고 SHA에서 불요한 록킹을 제거하여 데이타 전송속도를 향상시킬 수 있도록 한 것으로 RPU와 SHA와의 인터페이스 수단에 적용한다.The present invention transmits a SHA command word using a queue index and a command queue in driving SCSI drives through SHA, which is a SCSI controller connected to an RPU and a memory through an MFB bus. Receive SHA Attention Word using Attention Queue Index and Attention Queue to overcome communication obstacles between units and remove unnecessary locking in SHA to improve data transfer rate. Applied to interface means between RPU and SHA. do.

Claims (1)

큐테이블의 명령큐와 어텐션 큐를 RPU(4)와 SHA(5)가 서로 공유 엑세스 가능한 상태에서 RPU(4)가 SHA(5)를 인에이블 또는 디스에이블시키고 명령큐에 명령워드를 기록한 후 큐인덱스의 종료 여부 및 풀(Full)여부를 검색하면서 해당 SHAO 또는 SHA1에 인터럽트를 걸어서 명령워드를 전송하며, SHA(5)가 인터럽트를 인식하고 해당 채널에 대한 어텐션 큐를 리드해와서 큐가 비어있는가 및 인데스의 종료여부를 검색하면서 해당하는 어텐션워드를 어텐션 큐 인덱스와 어텐션 큐를 이용하여 수신함을 특징으로 하는 실시간 처리 유닛과 SHA의 인터페이스 제어방법.The RPU 4 enables or disables the SHA (5) and writes the command word to the command queue while the RPU (4) and the SHA (5) share access to each other. The command word is sent by interrupting the SHAO or SHA1 while searching whether the index is terminated and full, and the queue is empty because SHA (5) recognizes the interrupt and reads the attention queue for the channel. And receiving a corresponding attention word using an attention queue index and an attention queue while searching for termination of the indes. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
