Latest Patents

Cheng's latest patents include a "Method and system for master devices accessing slave devices." This patent discloses techniques for multiple master devices accessing one or more slave devices via a single data bus. The invention features a bus controller that is coupled between the master devices and the slave device. The bus controller is designed to receive bus signals from the master devices, select one of the bus signals, and forward it to the slave device. After receiving the bus signal, the slave device sends a bus response signal back to the master devices through the bus controller, allowing the master device to identify and receive the response.

Another significant patent is the "Method and apparatus for extending memory addressing." This invention presents techniques for extending memory addressing with a broader accessing range. The apparatus comprises a plurality of extended memories, each allocated a unique identifier. A direct addressing memory reserves a data cell as a public identifier cell for receiving the identifiers of the extended memories. A decision unit determines which extended memory to access by comparing the received identifier with those of the extended memories. The mapping unit then maps the selected extended memory onto the direct addressing memory for indirect access.
