Latest Patents

Vaccaro holds a patent for a "Programmable Systolic BCH Decoder." This invention provides both error and erasure decoding for all Reed-Solomon, primitive BCH, non-primitive BCH, and binary BCH codes of any rate over any field. The user can specify decoding parameters, including the code block-length, the code-generator polynomial, and the field-generator polynomial. The architecture is designed to be efficient, with a decoding processor that includes systolic arrays implementing a syndrome calculator, a key equation solver, a Chien search, a recursive extender, and an inverse transform. The design allows for scalability, as the systolic arrays can be fabricated on a single VLSI microchip and can be extended by arraying multiple microchips together.
