Abstract

본 발명은 수신한 데이터를 워드 단위로 변환하기에 적합한 데이터 변환 장치에 관한 것으로, 종래의 SBus 인터페이스에서는 바이트, 하프-워드 그리고 워드 크기의 데이터 처리가 가능함에도 불구하고 수신되는 데이터를 바이트 단위로 처리하기 때문에 결국, 워드 단위로 처리하는 것에 비해 속도나 시스템 효율이 떨어졌으나, 본 발명에서는 수신부(1)의 바이트 단위의 데이터를 저장부(7)에 수신부(1)의 바이트 단위의 데이터를 순차적으로 저장시켰다가 입출력부(12)를 통과시키면서 저장부(7)의 각 바이트 단위의 데이터가 동시에 출력되도록 하므로써 결국, 접속부(13)는 입출력부(12)로부터 데이터를 32비트의 데이터 단위 즉, 워드 단위로 인가 받게 되므로 다음단의 데이터 처리 속도가 향상되어 전체적인 시스템의 효율이 증대되므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to a data conversion apparatus suitable for converting received data in word units. In the conventional SBus interface, the received data is processed in bytes even though data of bytes, half-words and word sizes can be processed. As a result, although the speed and the system efficiency are inferior to processing in the word unit, in the present invention, the byte unit data of the receiver unit 1 is sequentially stored in the storage unit 7 in the byte unit data of the receiver unit 1. By storing and passing the data in each byte unit of the storage unit 7 while passing through the input / output unit 12, the connection unit 13 eventually converts the data from the input / output unit 12 into a 32-bit data unit, that is, a word. As the unit is authorized in units, the data processing speed of the next stage is improved to improve the efficiency of the overall system. It is capable.
