    摘要: A parallel data transmission test system can include a receiver section (100) having input selector circuits (104-0 to 104-N) that provide a received test data to logic adjust circuits (106-0 to 106-N) that “logically align” multiple incoming test values to remove intentionally introduced logic difference (e.g., inversion) with respect to one another. Result combining circuit (108) can logically combine output data values and provide a resulting sequence to a pattern sequence test circuit (110).

    摘要: A system and method for rendering multiple windows across multiple display planes utilizing a sliced rendering data pathway architecture for achieving a highly area efficient design of the graphics display system. Windows across multiple display planes are rendered from direct memory access fetch engines retrieving pixel data from memory. Rendering data pathways are shared between direct memory access fetch engines directed to a single display plane. Furthermore, the rendering data pathways can be time sliced wherein data from multiple planes are time multiplexed through the rendering pathway. The invention allows creating a graphical engine with a lower gate count than conventional circuits. The resultant system is modular and scalable, while being customizable from lower power applications to HDTV sets.
