Abstract: 본 발명에 따른 실용위성 시험장치는 명령데이터 입력부, 병렬/직렬 변환부, 인코더, 데이터 합성부, 파형 변환부 및 출력 선택부를 포함한다. 명령데이터 입력부는 명령구동 컴퓨터로부터의 기본 데이터를 소정의 기준 프로토콜의 형식에 맞도록 처리한다. 병렬/직렬 변환부는 명령데이터 입력부로부터의 명령데이터를 직렬 데이터로 변환시킨다. 인코더는 병렬/직렬 변환부로부터의 직렬 데이터에 상응하는 오류정정코드를 발생시킨다. 데이터 합성부는 병렬/직렬 변환부로부터의 직렬 데이터의 단위 프레임마다 인코더로부터의 오류정정코드를 부가한다. 파형 변환부는 데이터 합성부로부터의 직렬 신호의 파형을 기준 프로토콜의 형식에 맞도록 변환시킨다. 출력 선택부는, 파형 변환부로부터의 직렬 신호를 처리하여, 실용위성의 각 입력 채널에 상응하는 전송명령을 출력한다.

Abstract: PURPOSE: A hardware memory scrubber is provided to shorten scrub time and reduce load by performing the memory scrub with hardware in a memory system of a satellite. CONSTITUTION: A scrub control block(110) generates a scrub execution control signal for executing the scrub of a mass memory control FPGA(Field Programmable Gate Array)(200), a page generating signal for scrubbing each page of a memory, and an address needed for executing the scrub. A multiplexer block(120) transmits the address, the data, and the control signal of the scrub control block to the mass memory FPGA. The scrub control block comprises a control block generating the scrub control signal by checking the time for executing the scrub, an address generating block generating the address needed for the scrub, and a page generating block generating the control signal for selecting the scrub page of a mass memory.
