Method and apparatus for correcting cache profiling information in multi-pass simulator

An apparatus for correcting cache profiling information, the apparatus comprising:

• a first cache snap shot storage unit for storing a first cache snap shot comprising cache profiling information on a cache when a first process being executed by a cycle accurate simulator is terminated;
• a second cache snap shot storage unit for storing a second cache snap shot comprising the cache profiling information on the cache when a second process is executed in the cycle accurate simulator;
• an readjustment unit for comparing the second cache snap shot of the second process and the first cache snap shot of the first process to readjust any one value of a cache hit value and a cache miss value which are present in the second cache snap shot of the second process;
• and
• a correction unit for correcting the cache profiling information which is stored in the first cache snap shot of the first process by reflecting the readjusted values which are present in the second cache snap shot of the second process.
