  • Abstract
    We explore tradeoffs between organization and number of ALUs and clock frequency in a stream processor. The tool provides candidate low-power configurations and estimates of their real-time performance. The tool relates instruction-level, subword, and data parallelism to functional units´ organization and utilization. The exploration methodology is applicable to all embedded-processor designs in signal and media processing.
