A Modified Approach to Data Cache Management
Gary Tyson, Matthew Farrens, John Matthews, Andrew Pleszkun
As processor performance continues to improve, more emphasis must be placed
on the performance of the memory system.
In this paper, a detailed characterization of data cache behavior for
load instructions is given. We show that by selectively applying cache line
allocation according the characteristics of individual load instructions,
overall performance can be improved for both the data cache and the memory
system. This approach can improve some aspects of memory performance by as
much as 60 percent on existing executables.
