摘要： Power management for a multi-processor chip includes a centralized global power manager that monitors global power for the whole chip, and local power managers. Local power managers manage power for local blocks such as processor cores, caches, and memory controllers. When a local block executes an instruction or accesses memory, an event is generated and looked up in a local power estimate table. A local power estimate for that event is sent to the global power manager, which sums all local power estimates received from all local blocks. An exponential moving average (EMA) is generated and compared to a global power threshold. When global power is over the threshold, local targets are sent to power managers that generate and monitor local power averages that must remain under the local target. The local block is throttled by the local power manager to reduce power when the local target is exceeded.

摘要： A system and method for compressing and decompressing a texture image that: (1) compresses each texel to 8 bits, and when decompressed, each texel is of a quality comparable to a 256 color palettized image; (2) increases the efficiency of the decompression system and method by eliminating complex operations, e.g., multiplication; and (3) increases the efficiency of the system and method when switching between textures that use different palettes, when compared to conventional system and methods. The invention compresses a texture image, stores the compressed texture image, and quickly and efficiently decompresses the texture image when determining a value of a pixel. The texture image compression technique utilizes a palletized color space that more closely matches the colors in the texture image while allocating an unequal number of bits to the color channels. Each texel in the texture image is converted to an 8-bit value in the selected color space, and a decompression table is generated that represents the RGB values for the each texel stored in the selected color space. In order to map the texture image to the object, one or more texels that are associated with each pixel are decompressed. The present invention quickly and efficiently decompresses each texel using a hardware decompression unit. The decompression unit does not perform any multiplication operations.
