I have a problem. I dont understand the "64K Aliasing Conflict" in the "Intel Pentium 4 and Intel Xeon Processor Optimization (Reference manual)". I have also looked into the "VTune Performance Analyzer Help". My problem is that: in the explanation given by them, I cannot point any conflict with L1 cache. Could anybody help me? Attending to the VTune Performance Analyzer Im having serious problems with "64K Aliasing Conflicts" in my project.
