Abstract
본 발명은 가변 길이 코드 디코더에서 코드 워드에 해당하는 값을 롬 테이블에서 찾는 롬 테이블 선택회로에 관한 것이다.The present invention relates to a ROM table selection circuit for finding a value corresponding to a code word in a ROM table in a variable length code decoder.
본 발명은 코드 워드에 따라 해당 값을 찾는 롬 테이블을 코드 워드의 비트수에 따라 제1롬 테이블(25) 및 제2롬 테이블(26)로 나눔으로써 롬의 사이즈를 줄여 가격을 다운시키고, 또한, 전체적으로는 롬이 차지하는 면적을 줄일 수 있다.The present invention reduces the size of the ROM by dividing the ROM table that finds the corresponding value according to the code word into the first ROM table 25 and the second ROM table 26 according to the number of bits of the code word. As a whole, the area of ROM can be reduced.
