Latest Patents

One of his latest patents is a data storage system with a stale data detector and method of operation. This innovative system provides a low-cost, high-speed solution for data storage while ensuring word-by-word stale data detection. It avoids the need to read and write to a single memory location during a memory read operation. The system incorporates two flag data storage bits for each word location, in addition to the normal data storage bits. As blocks of data are received, one of the two flag bits is assigned to the block on an alternating basis. Upon writing data to an address location, the assigned flag bit is set to indicate valid data. When reading, the corresponding flag bit signals stale or invalid data, while the non-assigned flag bit is prepared for the next block of data.

Another notable patent is a data unpacker that utilizes a pack ratio control signal for unpacked parallel data. This device receives packed parallel input data words and outputs parallel data words of variable width. It employs an input register to store the received words and applies them to a bit shifter. The bit shifter shifts the data based on a control signal, allowing for flexible output widths. The unpacker is designed to handle varying data sizes efficiently, ensuring that the system is ready to receive and process new input data promptly.
