A method and system for using external storage to amortize CPU cycle utilization, wherein translated instructions are stored in a storage medium and subsequently accessed on a subsequent execution of a non-native application in order to amortize CPU cycles used in generating the translated instructions.

A request tracking data prefetch apparatus for a computer system is described. The apparatus includes a prefetcher coupled to a memory of the computer system. A tracker is coupled to the prefetcher, and is configured to recognize an access to a plurality of cache lines of the memory by a processor of the computer system. A cache memory is coupled to the prefetcher. The prefetcher predictively loads a target cache line of the memory into the cache memory. The target cache line for the predictive load is indicated by the tracker.

The described embodiments provide a system that encodes a sequence of integers using a variable-length compression technique. During operation, the system scans the sequence of integers and observes the sizes of the integers to determine a threshold value, K, from the observed sizes. For a given integer of length N bits, if N&#x2212;K is greater than zero, the system generates a tag for the encoded integer comprising a sequence of N&#x2212;K zeros followed by a one, and generates a set of remaining bits for the encoded integer as a sequence of the N&#x2212;1 least-significant bits which make up the integer. Otherwise, the system generates a tag for the encoded integer as a single one, and generates a set of remaining bits for the encoded integer by padding the N bits which make up the integer with zeros so that the set of remaining bits is K bits in length.

A method for using idiom recognition during a software translation process. The method includes accessing non-native instructions of a non-native application, determining whether an instruction pattern of the non-native instructions is recognized from a previous execution, if recognized, retrieving and executing translated instructions corresponding to the non-native instructions.
