摘要： A method and apparatus for improved double buffering within a computing system begins when a series of data blocks are received from a central processing unit at a rate independent of a processing rate of a recipient engine. For example, a video graphics circuit receives a series of data blocks representing video frames from the central processing unit at a rate independent of the refresh rate of the display. As the data blocks are received, the video graphics circuit queues commands of the data blocks. Typically, the commands include processing commands and a processing rate synchronize command. To process the data blocks, the co-processor pulls commands from the queued list and processes them to produce recipient data. As the co-processor is producing the recipient data, it is utilizing a first buffer. The co-processor continues to process the commands and storing the results into the first buffer until the processing rate synchronize command is detected. At this point, the co-processor pauses processing of the commands. At the beginning of the next cycle of the processing rate, the recipient data is provided from the first buffer to the recipient engine and the co-processor resumes processing of commands, which relate to another data block. As the co-processor is processing the commands of the second data block, it is utilizing a second buffer to store the processed data, i.e., the second recipient data.

摘要： A method and apparatus for improved concurrency within a video graphics process by generating culling information from geometry information. The geometry information corresponds to an image to be rendered, and the culling information indicates the triangles of the objects of the image that are in a front-facing or back-facing position. Having generated the culling information, set-up information is generated therefrom. The set-up information provides rendering data for the triangles of the object of the image being rendered. Next, pixel data is generated for a triangle based on the set-up information. To improve the concurrency, the queuing and the retrieval of the culling information and the set-up information from non-local memory are controlled such that the generating of the culling information, the set-up information, and the pixel data is done with improved concurrency.

摘要： A method and apparatus include processing which allows a graphics controller to extend its memory by receiving a client address and determining which of a plurality of system bus interfaces (e.g., AGP, PCI, ISA) is enabled. When a first type of system bus interface is enabled (e.g., PCI, ISA), a first system bus table index is generated based on the client address. The first system bus table index is used to access a first system bus table to retrieve a physical address of memory. The processing continues by obtaining data from the memory, wherein the data is stored at the physical address.

摘要： A technique for encoding and decoding video information uses a plurality of video processing modules (VPMs), whereby each video processing module is dedicated to a particular video processing function, such as filtering, matrix arithmetic operations, and the like. Information is transferred between the video processing modules using a set of first-in first-out (FIFO) buffers. For example, to transfer pixel information from a first VPM to a second VPM, the first VPM stores the pixel information at the head of a FIFO buffer, while the second VPM retrieves information from the tail of the FIFO buffer. The FIFO buffer thus permits transfer of information between the VPMs without storage of the information to a cache or other techniques that can reduce video processing speed.

摘要： A first data storage requirement of a first multimedia data representative of a multimedia program to be stored at a storage device is determined. An available remaining storage capacity of the storage device is determined. The first multimedia data is transcoded to generate a second multimedia data having a second data storage requirement that is less than the first data storage requirement if the first storage requirement exceeds the available remaining storage capacity of the storage device. Alternately, a second multimedia data stored at the storage device and representative of a second multimedia program is selected based on user preference information. The second multimedia data is transcoded to generate a third multimedia data having a lower data storage requirement. The third multimedia data is stored at the storage device in place of the second multimedia data to increase the available remaining storage capacity of the storage device.

摘要： A multimedia program type of a received multimedia data is determined. Based on the determined multimedia program type, a peak bit rate limit and/or an average bit rate limit are determined. In instances where a transrated version of the multimedia data is to be stored, a remaining storage capacity of a storage device is determined and the peak bit rate limit and/or the average bit rate limit can be adjusted based on the remaining storage capacity. The multimedia data then is transrated to generate transrated multimedia data that has a peak bit rate that does not exceed the selected peak bit rate limit and/or having an average bit rate that does not exceed the selected average bit rate limit. The transrating of the multimedia additionally can include the application of rule sets based on content characteristics. After transrating, the multimedia data can be transmitted via a network to a destination multimedia device, stored locally for subsequent use, or a combination thereof.

摘要： A local system encodes previously decoded video data using a transcoding quantization value based on a source quantization value provided by a previous encoder as part of the retrieved video data. The transcoding quantization value can be determined additionally based the fullness of the video buffer of a target system, where a measure of the fullness can be obtained directly from the target system or modeled by the local system. The video data is encoded by the local system and then provided to a target system for decoding and subsequent display and/or storage.
