Abstract
Description
Claims (3)
- 라이트 콘트롤러(6)의 제어신호에 의해 정해진 셀 헤더 버퍼로 ATM 셀 헤더를 저장하거나, 리드 콘트롤러(7)의 제어신호에 의해 정해진 버퍼에서 1비트씩 데이터를 출력하는 ATM 셀 헤더 버퍼(2)와;입력 셀의 시작을 알리는 신호(SOC-IN)와 인터리버 신호(INT-CON)를 이용해서 셀의 헤더와 페이로드를 분리 저장하도록 제어하는 라이트 콘트롤러(6);인터리버 메모리(3)에서 헤더와 페이로드가 섞여 출력되는 데이터 중 순서에 따라 출력되도록 제어하는 리드 콘트롤러(7);9개의 버퍼로 ATM 셀의 페이로드 데이터를 라이트 콘트롤러(6)에서 보내는 제어신호에 의해 정해진 곳에 쓰는 한편, 헤더 비트가 섞여진 12 바이트의 데이터를 출력하고, 멀티플렉서(4)를 거쳐 최종적으로 인터리버 된 ATM셀이 되도록 하는 인터리버 메모리(3);이 인터리버 메모리(3)에서 출력되는 12 가지 종류의 데이터를 리드 콘트롤러(7)의 제어신호에 의해 멀티플레싱하게 되는 멀티플렉서(4)를 포함하여 구성되어짐을 특징으로 하는 8 비트 병렬 셀 단위 인터리버.
- 제 1항에 있어서, 이 인터리버 메모리(3)는 9개의 단위 버퍼 중의 데이터를 쓰기 위한 한 곳을 선택하는 디코더(3a)와, 9 바이트 입력을 10 바이트로 바꾸어 주는 컨버터(3b)로 구성되어짐을 특징으로 하는 8 비트 병렬 셀 단위 인터리버.
- 제 2항에 있어서, 이 컨버터(3b)는 9개의 바이트가 저장되게 되는 D 플립/플롭(3b-1)(3b-2)와, 9 바이트의 데이터가 한 바이트의 헤더와 섞여서 10 바이트가 되게 하는 믹서(3b-3)로 구성되어짐을 특징으로 하는 8 비트 병렬 셀 단위 인터리버.
