    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.

    摘要: Embodiments of the present invention provide a memory controller comprising a front-end module, a back-end module communicatively coupled to the front-end module, and a physical interface module communicatively coupled to the back-end module. The front-end module generates a plurality of page packets from a plurality of received memory commands, wherein the order of receipt of said memory commands is preserved. The back-end module dynamically issues a next one of the plurality of page packets while issuing a current one of the plurality of page packets. The physical interface module causes a plurality of transfers according to the dynamically issued current one and next one of the plurality of page packets.
