摘要： A method and apparatus for graphics rendered in a mobile device includes a command queue capable of receiving a plurality of rendering commands, a generate_event command and a wait_until command. The wait_until command corresponds to the completion of a specific operation indicated by the generate_event command. The method and apparatus further includes a direct memory access device operably coupled to the command queue, wherein the DMA device is capable of receiving a memory access command in response to the generate_event command. A memory device is capable of storing rendering information, wherein the memory device is accessible in response to the generate_event command. Furthermore, the method and apparatus includes the command queue capable of queuing the rendering commands in response to the wait_until command until the completion of the operation indicated by the generate_event command.

摘要： A memory system and method uses common memory for multiple controllers associated with, for example, differing data manipulation functions, such as video graphics related functions or other suitable functions. A multiplexer, configured as a time slicer, selects data for transfer with the memory over a first bus at a first rate. The multichannel serializer is coupled between the multiplexer and a plurality of controllers through a plurality of second buses. Each of the second buses is associated with a different channel. The multichannel serializer has a serializer for each of the plurality of second buses wherein each of the serializers transfers data associated with a channel at a second rate associated with a corresponding controller.

摘要： A display FIFO memory management system and method includes a programmable FIFO emulator for emulating a drain and fill time of the display FIFO memory to automatically predict a number of register entries remaining in the display FIFO memory at each predefined clock cycle. A programmable timer/counter has programmable precision to accommodate varying bandwidths of display screen display modes and is used to determine the number of entries remaining so that the emulator can accommodate varying screen display modes. A FIFO controller controls the timing of fetching display data from memory to fill the display FIFO memory based on the prediction of the number of remaining register entries in the display FIFO by the programmable emulator.

摘要： A specific embodiment is disclosed for a method and apparatus for processing data access requests from a requesting device, such as a graphics processor device. Data access commands are provided at a first rate, for example 200M commands per second, to a memory bridge. In response to receiving the access requests the memory bridge will provide its own access requests to a plurality of memories at approximately the first rate. In response to the memory bridge requests, the plurality of memories will access a plurality of data at a second data rate. When the data access between the memory bridge and the memories is a read request, data is returned to the requesting device at a third data rate which is greater than the first data rate by approximately four-times or more. Noise and power reduction techniques can be used on the data bus between the accessing device and the data bridge.

摘要： A multiple pipeline memory controller has a plurality of two stage pipeline processors dedicated to separately process real time video capture and display refresh input request signals. A separate pipeline processor processes non-real time input signals. The multiple pipeline design reduces memory access latency and improves throughput of data in display FIFO memory to effect improved resolution. The multiple pipeline memory controller can be integrated in a video graphics controller (VGC).
