ABSTRACT:
A single unified level one instruction cache in which some lines may contain traces and other lines in the same congruence class may contain blocks of instructions consistent with conventional cache lines. Power is conserved by guiding access to lines stored in the cache and lowering cache clock speed relative to the central processor clock speed.
