Latest Patents
One of Masaki Nasu's latest patents is for a multiprocessor computer system that features bus control circuitry. This innovative system includes first and second microcomputers, an address decoding mechanism, and a ready signaling device. The address decoder is connected to an address bus, decoding address information from the second microcomputer and supplying a request signal to the first microcomputer. The bus control unit of the first microcomputer detects whether its internal bus is available and outputs an acknowledge signal when it is free. The ready signaling device then provides a ready signal to the second microcomputer based on the acknowledge signal and the request signal. This invention streamlines data read/write operations and enhances overall system performance.
Another notable patent by Nasu is an interrupt controller with a selectable interrupt nesting function. This controller holds information about designated priorities for multiple interrupt requests. It features a flag that indicates whether nesting is allowed for an interrupt request with a predetermined priority. The controller operates based on the priority information and the flag's condition, acknowledging generated interrupt requests according to their priority levels. This innovation improves the handling of interrupt requests, making systems more responsive and efficient.
