Abstract: An integrated circuit chip configured to be coupled to a single shared memory including, in combination, a memory access module, at least one video signal processing module, and a frame rate converter, wherein the memory access module is configured to coordinate access to the single shared memory by the at least one video signal processing module and the frame rate converter.

Abstract: A method and apparatus for a multi-chip module that is testable and reconfigurable based on testing results is accomplished by a multi-chip module that includes a first circuit disposed on a first chip substrate, a second circuit disposed on second chip substrate, and an interconnecting substrate operably coupled to the first chip substrate and the second chip substrate. The interconnecting substrate connects the first circuit to the second circuit. The interconnecting substrate includes external connectors for accessing signals within the multi-chip module, which allow the multi-chip module to be fully tested. This testing may include isolating the first circuit and/or the second circuit by disabling other circuits in order to allow each of the circuits to be exercised without interference from other circuits. After testing the multi-chip module, configuration circuitry included on the multi-chip module may be used to reconfigure the multi-chip module based on results of the testing.

Abstract: A clocking control circuit for a computer system and method for receiving a microprocessor clock signal which drives a microprocessor and for supplying a support clock signal having a lower frequency. The support clock frequency drives support interface circuitry such as a peripheral controller, a CPU/memory controller, and a bus bridge interface, and thus causes the support interface circuitry to operate at a lower frequency than the microprocessor. The clocking control circuit ensures synchronization between the support clocking signal and the microprocessor clocking signal. The transmission of control signals between the microprocessor and support interface circuitry is controlled to ensure proper communications between the microprocessor and support circuitry.
