摘要:
Page size prediction is used to predict a page size for a page of memory being accessed by a memory access instruction such that the predicted page size can be used to access an address translation data structure. By doing so, an address translation data structure may support multiple page sizes in an efficient manner and with little additional circuitry disposed in the critical path for address translation, thereby increasing performance.

A method and apparatus for efficiently storing an effective address (EA) in an effective to real address translation (ERAT) table supporting multiple page sizes by adding PSI fields, based on the number of unique page sizes supported, to each ERAT entry and using one ERAT entry to store an EA for a memory page, regardless of page size, by setting the PSI fields to indicate the page size.
摘要:
The present invention provides for a method for a load address dependency mechanism in a high frequency, low power processor. A load instruction corresponding to a memory address is received. At least one unexecuted preceding instruction corresponding to the memory address is identified. The load instruction is stored in a miss queue. And the load instruction is tagged as a local miss.

A method and system in accordance with the present invention provides an intelligent prediction approach for populating and depopulating multiple applications at the system level across applications. The detection and management of user behavior patterns to anticipate the user's next request is provided. Further the present invention is to account for a situation to relate dynamically to user behavior and where that user behavior changes to adjust so as to more accurately set forth a desired result for a user of the present invention. The present invention in various implementations provides an intelligent prediction scheme for populating and depopulating multiple applications at the system level across a diversity of applications.
摘要:
A method is disclosed for executing a load instruction. Address information of the load instruction is used to generate an address of needed data, and the address is used to search a cache memory for the needed data. If the needed data is found in the cache memory, a cache hit signal is generated. At least a portion of the address is used to search a queue for a previous load instruction specifying the same address. If a previous load instruction specifying the same address is found, the cache hit signal is ignored and the load instruction is stored in the queue. A load/store unit, and a processor implementing the method, are also described.

Methods for executing load instructions are disclosed. In one method, a load instruction and corresponding thread information are received. Address information of the load instruction is used to generate an address of the needed data, and the address is used to search a cache memory for the needed data. If the needed data is found in the cache memory, a cache hit signal is generated. At least a portion of the address is used to search a queue for a previous load and/or store instruction specifying the same address. If such a previous load/store instruction is found, the thread information is used to determine if the previous load/store instruction is from the same thread. If the previous load/store instruction is from the same thread, the cache hit signal is ignored, and the load instruction is stored in the queue. A load/store unit is also described.
