摘要： A computer system and method for providing cache memory management. The computer system comprises a main memory having a plurality of main memory addresses each having a corresponding data entry, and a processor coupled to the main memory. At least one cache memory is coupled to the processor. The at least one cache memory has a cache directory with a plurality of addresses and a cache controller having a plurality of data entries corresponding to the plurality of addresses. The processor receives an instruction having an operand address and determines if the operand address matches one of the plurality of addresses in the cache directory. If so, the processor updates a data entry in the cache controller corresponding to the matched address. Otherwise, a data entry corresponding to the operand address in the main memory is updated.

摘要： An apparatus and method for performing an intra-add operation on packed data using computer-implemented steps is described. A processor is coupled to a hardware unit which transmits data representing graphics to another computer or display. A storage device coupled to the processor, has stored therein a routine, which, when executed by the processor, causes the processor to generate the data. The routine causes the processor to at least access a first packed data operand having at least one pair of data elements; swap positions of the data elements within the at least one pair of data elements to generate a second packed data operand, add data elements starting at the same bit positions from the first and second packed data operands to generate a third packed data operand.

摘要： An apparatus and method for a power-efficient framework to maintain data synchronization of a mobile personal computer (MPC) are described. In one embodiment, the method includes the detection of a data synchronization wakeup event while the MPC is operating according to a sleep state. Subsequent to wakeup event, at least one system resource is disabled to provide a minimum number of system resources required to re-establish a network connection. In one embodiment, user data from a network server is synchronized on the MPC without user intervention; the mobile platform system resumes operation according to the sleep state. In one embodiment, a wakeup alarm is programmed according to a user history profile regarding received e-mails. In a further embodiment, data synchronizing involves disabling a display, and throttling the system processor to operate at a reduced frequency. Other embodiments are described and claimed.
