MEMORY-AREA PROPERTY STORAGE INCLUDING DATA FETCH WIDTH INDICATOR

摘要

Embodiments relate to memory-area property storage including a data fetch width indicator. An aspect includes allocating a memory page in a main memory to an application that is executed by a processor of a computer. Another aspect includes determining the data fetch width indicator for the allocated memory page. Another aspect includes setting the data fetch width indicator in the at least one memory-area property storage in the allocated memory page. Another aspect includes, based on a cache miss in the cache memory corresponding to an address that is located in the allocated memory page: determining the data fetch width indicator in the memory-area property storage associated with the location of the address; and fetching an amount of data from the memory page based on the data fetch width indicator.

1. A computer system for memory-area property storage including a data fetch width indicator, the system comprising:
a processor; a cache memory; and a main memory comprising a plurality of memory pages, each of the memory pages comprising at least one respective memory-area property storage, the system configured to perform a method comprising:
allocating a memory page in the main memory to an application that is executed by the processor;determining the data fetch width indicator for the allocated memory page;setting the data fetch width indicator in the at least one memory-area property storage in the allocated memory page; andbased on a cache miss in the cache memory corresponding to an address that is located in the allocated memory page:
determining the data fetch width indicator in the memory-area property storage associated with the location of the address; andfetching an amount of data from the memory page based on the data fetch width indicator.
