Latest Patents

Howard M. Shao holds a patent for "Architecture for time or transform domain decoding of Reed-Solomon codes." This patent describes a system that utilizes two pipeline (255,233) Reed-Solomon decoders. One decoder operates in the time domain while the other functions in the transform domain. Both decoders share a common first part to develop an errata locator polynomial, denoted as .tau.(x), and an errata evaluator polynomial, A(x). The design incorporates a modified GCD that employs an input multiplexer and an output demultiplexer to minimize the number of GCD cells required. The time domain decoder implements a Chien search and polynomial evaluator on the GCD outputs .tau.(x) and A(x) for final decoding steps. In contrast, the transform domain decoder utilizes a transform error pattern algorithm operating on .tau.(x) and the initial syndrome computation S(x), followed by an inverse transform algorithm to produce a decoded output message.
