M64403FP

IMIN PREL ARY MITSUBISHI ICs (LSI) . ication hange. c l specif t a fina re subject to o n is a its :This Notice arametric lim p Some M64403FP ERROR CORRECTION WITH VARIABLE LENGTH AND DISTANCE DESCRIPTION The M64403FP performs the decoding for RS (Reed Solomon) code which primitive polynomial:P (X)=X8+X4+X3+X2+1 and its generation polynomial:G (X)=Π (X-αj). M64403FP can set the code length and check byte length, so it is able to be adopted to various systems. j=0 d-2 APPLICATION DVD player, DVD-ROM (DVD:Digital Video Disc), DBS (Direct Broadcasting by Satellite), High density floppy disk, Hard disk, CATV (Cable TV), MD (Mini Disc), DVC (Digital Video Cassette), DAT (Digital Audio Cassette), DCC (DIgital Compact Cassette), DVB (Digital Video Broadcast), CD-DA (Compact Disc-Digital Audio), CD-ROM (Compact Disc-Read Only Memory), other communication systems and storage media etc. FEATURES It adopts three stages pipe line operation (Syndrome stage, Euclidean stage, Chen search & error value stage), so it realizes high speed error correction operation. Capable of erasure correcting function and it improves error correction performance. Where error counts (e), erasure counts (ε) and design distance (d) have followed restriction. 2e + ε < d Capable of parameter register programing. (1) Four kinds of code parameter which code length and check byte length are programmable. (Good for the product code that has plural code parameters.) Where, maximum code length (L) are 255 by...
