In one embodiment, the present invention includes a method for receiving a cache access request for data present in a lower-level cache line of a lower-level cache, and sending recency information regarding the lower-level cache line to a higher-level cache. The higher-level cache may be inclusive with the lower-level cache and may update age data associated with the cache line, thus reducing the likelihood of eviction of the cache line. Other embodiments are described and claimed.

A method is disclosed. The method includes scheduling a load operation at least twice the size of a maximum access supported by a memory device, dividing the load operation into a plurality of separate load operation segments having a size equivalent to the maximum access supported by the memory device, and performing each of the plurality of load operation segments. A further method is disclosed where a temporary register is used to minimize the number of memory accesses to support unaligned accesses.

In one embodiment, the present invention includes a method for executing an operation on low order portions of first and second source operands using a first execution stack of a processor and executing the operation on high order portions of the first and second source operands using a second execution stack of the processor, where the operation in the second execution stack is staggered by one or more cycles from the operation in the first execution stack. Other embodiments are described and claimed.

A low cost, low power consumption scalable architecture is provided to allow a computer system to be managed remotely during all system power states. In a lowest power state, power is only applied to minimum logic necessary to examine a network packet. Power is applied for a short period of time to an execution subsystem and one of a plurality of cores selected to handle processing of received service requests. After processing the received service requests, the computer system returns to the lowest power state.

Techniques for vector completion mask (VCM) handling are provided. A data structure includes a mask field for each operand of a particular operation. A processor attempts to execute the operation with multiple operands, which are identified in the data structure by the mask fields. If operands are successfully retrieved for execution with the operation, then the corresponding mask field within the data structure is cleared. The processor can reset if any field remains set within the data structure and can re-process the operation with operands that were not previously handled with the operation.
