    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: A speculative transfer mechanism transfers a source synchronous read request from a first clock domain to a second clock domain. The address portion having address information is transferred to the second clock domain in response to detecting a source synchronous address strobe latching signal. A pointer is generated in response to detecting the address strobe latching signal and passed into the second clock domain. In one embodiment, a pointer is retimed to be stable for a timing window for which a crossover of the address portion may be performed in the second clock domain. Request logic in the second clock domain generates a read command based on the address portion and the pointer.
