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 μm CMOS single-poly double-metal (SPDM) standard cells. The chip size is 4.22×3.64 mm2 with a core area of 2.90×2.88 mm mm2, where the total gate count is about 26 K. Test results show that the proposed RS-PC decoder chip can support 4×DVD speed with off-chip frame buffers or 8×DVD speed with embedded frame buffers operating at 3 V
