摘要： Disclosed is an apparatus to reduce broadcasts in multiprocessors including a plurality of processors; a plurality of memory caches associated with the processors; a plurality of translation lookaside buffers (TLBs) associated with the processors; and a physical memory shared with the processors memory caches and TLBs; wherein each TLB includes a plurality of entries for translation of a page of addresses from virtual memory to physical memory, each TLB entry having page characterization information indicating whether the page is private to one processor or shared with more than one processor. Also disclosed is a computer program product and method to reduce broadcasts in multiprocessors.

摘要： A memory system and method includes a cache having a filtered portion and an unfiltered portion. The unfiltered portion is divided into block sized components, and the filtered portion is divided into sub-block sized components. Blocks evicted from the unfiltered portion have selected sub-blocks thereof cached in the filtered portion for servicing requests.

摘要： A memory storage structure includes a memory storage device, and a first meta-structure having a first size and operating at a first speed. The first speed is faster than a second speed for storing meta-information based on information stored in a memory. A second meta-structure is hierarchically associated with the first meta-structure. The second meta-structure has a second size larger than the first size and operates at the second speed such that faster and more accurate prefetching is provided by coaction of the first and second meta-structures. A method is provided to assemble the meta-information in the first meta-structure and copy this information to the second meta-structure, and prefetching the stored information from the second meta-structure to the first meta-structure ahead of its use.

摘要： An apparatus for memory access prediction which includes a plurality of processors, a plurality of memory caches associated with the processors, a plurality of saturation counters associated with the processors, each of the saturation counters having an indicator bit, and a physical memory shared with the processors, saturation counters and memory caches. Upon a cache miss for a data item, a cache snoop and access to physical memory are initiated in parallel for the data item if the indicator bit is a first predetermined bit (one (1) or zero (0)) whereas a cache snoop is initiated if the most significant bit is a second predetermined bit (zero (0) or one (1)).

摘要： Disclosed is a method and apparatus providing the ability to create a multi-level prediction algorithm, whereby branch predictions beyond the first level of prediction are maintained at a secondary level because the prior level was unsuccessfully able to highly predict the direction of the stated branch accurately. A secondary level is smaller in size than the upper level through selected filtering thereby enabling high prediction accuracy of branches while minimizing the amount of hardware required to perform stated predictions.
