摘要： In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for implementing a balanced P-LRU tree for a “multiple of 3” number of ways cache. For example, in one embodiment, such means may include an integrated circuit having a cache and a plurality of ways. In such an embodiment the plurality of ways include a quantity that is a multiple of three and not a power of two, and further in which the plurality of ways are organized into a plurality of pairs. In such an embodiment, means further include a single bit for each of the plurality of pairs, in which each single bit is to operate as an intermediate level decision node representing the associated pair of ways and a root level decision node having exactly two individual bits to point to one of the single bits to operate as the intermediate level decision nodes representing an associated pair of ways. In this exemplary embodiment, the total number of bits is N−1, wherein N is the total number of ways in the plurality of ways. Alternative structures are also presented for full LRU implementation, a “multiple of 5” number of cache ways, and variations of the “multiple of 3” number of cache ways.

摘要： In a computer system including a plurality of resources, a device receives a request from a software program to access a specified one of the plurality of resources, determines whether the specified one of the plurality of resources is a protected resource. If the specified one of the plurality of resources is a protected resource, the device denies the request if the computer system is operating in a protected mode of operation, and processes the request based on access rights associated with the software program if the computer system is not operating in the protected mode of operation.

摘要： Duplicate record processing is enabled employing on customizable rules. Detected duplicate records are merged, deleted, deactivated, or moved based on one or more sets of customizable rules. Different rule sets may be used for each record type, or a rule set reused for different records. Hierarchical relationships between master and child records are adjusted upon duplicate processing based on rules and/or record attributes.

摘要： The present invention relates to an improved microprocessor having a memory system with several caches that can be operated to provide virtual memory. Among the caches included in the microprocessor are conventional caches that store data and instructions to be utilized by the processes being performed by the microprocessor, and that are typically arranged in a cache hierarchy, as well as one or more translation lookaside buffer (TLB) caches that store a limited number of virtual page translations. The improved microprocessor also has an additional cache that serves to store a virtual hash page table (VHPT) that is accessed when TLB misses occur. The introduction of this VHPT cache eliminates or at least reduces the need for the microprocessor to look for information within the caches of the cache hierarchy or in other memory (e.g., main memory) outside of the microprocessor when TLB misses occur, and consequently enhances microprocessor speed.
