Latest Patents

One of his latest patents involves a method for comparing an estimated CRC syndrome to a generated CRC syndrome. This invention addresses the occurrence of uncorrectable errors in a stored sector of data, which includes a data block, an error checking and correcting (ECC) block, and a CRC block. The ECC logic is connected to a data bus and generates an error polynomial that identifies the location and value of correctable errors. The CRC logic, also connected to the data bus, generates a syndrome that identifies detected errors in the data block. An evaluation logic circuit is included to generate an uncorrectable error signal if the detected errors do not match the correctable errors. This invention utilizes Reed-Solomon codes as per the X3B11 standard.

Another notable patent by Yu is for a bit map rotation processor. This apparatus is designed for rotating bit-mapped data and includes a specially designed data array that features both a normal port for accessing horizontal words of data and a rotated port for accessing vertical words. The address generating logic automatically creates proper address sequences for accessing the appropriate words during a rotation operation. This innovative apparatus is cascadable, allowing for the effective creation of any size data array.
