A Reed-Solomon Product-Code (RS-PC) decoder chip for DVD applications

Abstract

In this paper, a Reed-Solomon Product-Code (RS PC) decoder for DVD applications is presented. It mainly contains two frame-buffer controllers, a (182, 172) row RS decoder, and a (208, 192) column RS decoder, The RS decoder features an area-efficient key equation solver using a novel modified decomposed inversionless Berlekamp-Massey algorithm. The proposed RS-PC decoder solution was implemented using 0.6-mum CMOS single-poly double-metal (SPDM) standard cells. The chip size is 4.22 x 3.64 mm(2) with a core area of 2.90 x 2.88 mm(2),where the total gate count is about 26K, Test results show that the proposed RS-PC decoder chip can support 4x DVD speed with off-chip frame buffers or 8x DVD speed with embedded frame buffers operating at 3 V.
