摘要: One embodiment of the invention sets forth a technique for compressing and storing display data and optionally compressing and storing cursor data in a memory that is local to a graphics processing unit to reduce the power consumed by a mobile computing device when refreshing the screen. Compressing the display data and optionally the cursor data also reduces the relative cost of the invention by reducing the size of the local memory relative to the size that would be necessary if the display data were stored locally in uncompressed form. Thus, the invention may improve mobile computing device battery life, while keeping additional costs low.

摘要: Display data and video data are stored within a graphics processing unit to reduce power consumed by the computing device during video playback. Storing display data and video data within the GPU reduces power consumption, because bus transaction activity is reduced and the need to read data from a larger, common main memory is avoided.

摘要: Display data used in display frame generation are compressed for efficient storage in a local memory within a graphics processing unit. The compression technique used is difference encoding and before performing difference encoding, display data in RGB format are converted into YCbCr format. Since the component values of adjacent pixels in YCbCr format typically vary less than the component values of the same adjacent pixels in RGB format, converting the display data to YCbCr format before performing difference encoding improves the compression efficiency.

摘要: A system, apparatus, and method are disclosed for predicting accesses to memory. In one embodiment, an exemplary apparatus comprises a processor configured to execute program instructions and process program data, a memory including the program instructions and the program data, and a memory processor. The memory processor can include a speculator configured to receive an address containing the program instructions or the program data. Such a speculator can comprise a sequential predictor for generating a configurable number of sequential addresses. The speculator can also include a nonsequential predictor configured to associate a subset of addresses to the address and to predict a group of addresses based on at least one address of the subset, wherein at least one address of the subset is unpatternable to the address.
