Latest Patents
One of Yasuhara's latest patents is a data storage system and control method designed to mitigate the risks associated with local disasters. This system arranges hard discs in a disc array at distant locations to prevent simultaneous damage and reduce recovery time during hard disc failures. The design allows for continuous operation even in the event of other disasters. Data is written from a server device and mapped using the RAID method, distributing data packets with RAID information and error correction codes across the hard discs. Additionally, the line connection device facilitates data transfer while maintaining RAID control, ensuring that the main control device can monitor hard disc devices and manage data recovery processes effectively.
Another notable patent addresses the control of conflicts between MPC transfer and DMC transfer by measuring instruction execution time. This data transfer control apparatus manages conflicts on a data bus connected to a microprocessor through a bridge circuit. The monitoring unit within the bridge circuit measures the time the data bus is occupied during MPC transfer and ensures that DMA transfer is not suspended, allowing for efficient data management.
