<p>PROBLEM TO BE SOLVED: To perform the various evaluation of debugging or the like utilizing information relating to a built-in cache memory in a semiconductor device functioning as a microprocessor. SOLUTION: In an emulation chip 10 provided with a cache memory 12 for temporarily storing the information accessed in a processor block 11 and a cache controller 13, as emulator dedicated terminals, a small number of cache hit signal terminals 16a, a cache mishit signal terminal 17a and an entry information/WAY information terminal 15a are provided. Every time of a cache hit/cache mishit, entry information/WAY information 15 is recorded, the entry information/WAY information 15 is converted to an address bus/data bus value at the time of the cache hit and displayed by utilizing the address bus/data bus value obtained through normal address bus terminal 14a and data bus terminal 18a in cache fill at the time of the cache mishit and thus, debugging is performed.</p> |
