Estimating the term…
Embodiments of the inventions are directed towards a computer-implemented methods and systems for determining an oldest logical memory address. The method includes creating an M number of miss request registers and an N number of stations in a load/store unit of the processor. In response to load requests from target instructions, a processor detects each L1 cache miss. The processor stores data related to each L1 cache miss in a respective miss request register. The data includes an age of each L1 cache miss and a portion of a logical memory address of the requested load. The processor stores the entire logical memory addresses of the requested loads in respective stations based on an age of the load requests. The processor transmits the oldest logical memory address that is stored at the stations.
A computer-implemented method for determining a logical address of an oldest load request, the method comprising:
A system for determining a logical address of an oldest outstanding load request, the system comprising:
A computer program product for determining a logical address of an oldest outstanding memory request, the computer product comprising a computer readable storage medium having program instructions embodied therewith, the instructions executable by a processor to cause the processor to:
