Abstract
A method and data processing system for accessing an entry in a memory array by placing a tag memory unit () in parallel with an operand adder circuit () to enable tag lookup and generation of speculative way hit/miss information () directly from the operands () without using the output sum of the operand adder. PGZ-encoded address bits (0:51) from the operands () are applied with a carry-out value (Cout) to a content-addressable memory array () to generate two speculative hit/miss signals. A sum value (EA) computed from the least significant base and offset address bits determines which of the speculative hit/miss signals is selected for output ().
