Abstract:
1. A cache memory for use in a computer system having more than one word length wherein a first of said more than one word lengths is a longer length word than a second of said more than one word lengths which is a shorter length word, said cache memory comprising: a data cache; an extended data queue; and logic, wherein the data cache stores a first portion of a word directed to or through said cache memory, and the extended data queue stores a second portion of the word directed to or through said cache memory, the second portion of the word being of a length equal to or less than a difference between said longer and shorter length words, and wherein the logic determines whether the second portion of the word is valid by analyzing the second portion of the word from the extended queue with an OR operation, and discards the second portion of the word if it is determined to be invalid.
