Title: Innovations by Vipul Srivastava
Introduction
Vipul Srivastava is a notable inventor based in San Jose, CA. He has made significant contributions to the field of data storage and error correction technologies. With a total of 4 patents to his name, his work has had a substantial impact on improving data integrity in digital systems.
Latest Patents
One of his latest patents is titled "Techniques for performing reduced complexity Galois field arithmetic for correcting errors." This invention provides methods for performing Galois field arithmetic to detect errors in digital data stored on disks. The techniques involve multiplying two 12-bit or two 10-bit numbers in Galois field using tower arithmetic. In the 12-bit embodiment, the base field GF(2) is extended through several quadratic extensions, while the 10-bit embodiment follows a similar process with fewer extensions. The use of irreducible polynomials is crucial in generating these extensions.
Another significant patent is "Error correction/detection code adjustment for known data pattern substitution." This invention offers techniques for updating cyclic redundancy check (CRC) bytes for data sectors that have been reassigned to a new logical block address (LBA). Instead of recalculating the entire set of CRC check bytes, only the affected portions are updated. This is achieved through an exclusive OR function on the old and new LBAs, followed by Galois Field multiplication to generate the updated CRC bytes.
