Latest Patents

One of his latest patents is for a high-speed flexible slave interface for a parallel common bus to local. This invention provides an interface for transferring data via a PCI bus between an initiator device and a host target that has a local cache buffer. The design includes an interface controller, an address resolution unit, data and address logic, byte enable logic, and command processing logic. These components work together to resolve address hits and misses, determining when write operations occur to the local cache buffer. The interface controller manages handshaking operations between the PCI interface and the initiator device, regulating data transfer and providing status signals during the transfer cycle. Additionally, the data logic verifies parity and provides data and parity information to the cache buffer.

Another significant patent involves a CPU with a pipelined instruction unit and effective address calculation. This prefetch unit includes a Branch history table that indicates the occurrence of a Branch instruction with a previously taken Target Address. It utilizes Branch mark bits stored in an instruction queue, allowing for efficient instruction prefetching. The prefetch unit also generates physical addresses for data cache access and provides effective address generation on an instruction-by-instruction basis.
