Title: Innovations by Katsuhiko Nakagawa
Introduction
Katsuhiko Nakagawa is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of data processing, holding a total of 3 patents. His work focuses on improving the efficiency and speed of data processing systems.
Latest Patents
One of Nakagawa's latest patents is a data processing apparatus that features a working memory area. This innovative apparatus includes a latch circuit positioned between a processing unit and a memory. The processed data produced by the processing unit is temporarily stored in the latch circuit, rather than being directly written into the memory. This allows for a write operation of the processed data to occur in parallel with a read operation, significantly enhancing processing speed. Additionally, the processed data can be directly transferred to the processing unit without needing to be written into the memory first.
Another notable patent is a data processor that includes a testing structure for a barrel shifter. This processor receives input data at its input terminals and produces shifted data at its output terminals based on shift control data. The shifted data is temporarily stored in a storage circuit, which returns the data to the output terminals in response to a test-enable signal. Feedback data derived from the input terminals is compared with the input data to determine if both sets of data are identical.
