A Reed-Solomon product-code (RS-PC) is used in digital versatile disk (DVD) for error correction to mitigate the errors introduced during manufacturing or by user damage. The RS-PC decoder chip contains two frame buffer controllers that interface with two off-chip frame buffers, a row RS decoder and a column RS decoder. The parallel architecture minimizes the amount of frame buffer access and timing constraints on the RS decoders. Each RS decoder contains a syndrome calculator, a key equation solver, a Chien search and an error value evaluator. The 4.22×64 mm2 chip with a 2.90×2.88 mm2 core uses a cell library in a 0.6 μm SPDM CMOS process.
