Abstract:
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)).
