Abstract This paper proposes a low-energy solution for CAM-based highly associative I-caches using a segmented word-line and a predictor-based instruction fetch mechanism. Not all instructions in a given I-cache fetch are used due to branches. The proposed predictor determines which instructions in a cache access will be used and does not fetch any other instructions. Results show an average I-cache energy savings of 44% over the baseline case and 6% over the segmented case with no negative impact on performance.
