Abstract
A cache controller unit includes an address comparator unit for comparing an address to be accessed in memory with a tag address. An invalid pattern comparator is coupled to the address comparator. The invalid pattern comparator operates to compare the tag address with an invalid pattern. A qualifier unit is coupled to the address comparator and the invalid pattern comparator. The qualifier unit outputs a signal when the address to be accessed in the memory matches the tag address in the address tag and the address tag does not match the invalid pattern.
