Description

ABSTRACT:
In one embodiment, a wordline decoder provides access to cache memory locations when addresses are bypassed directly from arithmetic circuitry in redundant form. The wordline decoder is also designed to provide access to cache memory locations when addresses are received from registers in an unsigned binary form. The combined functionality is provided in a pre-decode circuit by selectively replacing one of a plurality of redundant bit vectors with a constant bit vector when redundant addressing is not enabled.
