Techniques for fast simulation of associative cache directories

We describe a technique for simulating associative cache
directories that considerably reduces simulation time with
respect to a sequential search of the tag array. We also
describe techniques for maintaining LRU information that use
considerably less memory than time-stamps. The combination
of these techniques makes possible the simulation of
set-associative cache directories at a much higher speed
than other techniques.
