ABSTRACT:
A multilevel set associative cache system whose directory and cache store are organized into levels of memory locations includes control apparatus which selectively degrades cache operation in response to error signals from directory error checking circuits to those levels detected to be free from errors. Test control apparatus which couples to the directory error checking apparatus operates to selectively enable and disable the directory error checking circuits in response to commands received from a central processing unit so as to enable the testing of the cache directory and other portions of the cache system using common test routines.
