5.5.4 Power Results for IDCT Column Bench Mark Table 5-20 summarizes the power consumed by the chip for every stripe in the SuperCISC reconfigurable hardware fabric design when the IDCT (Inverse Discrete Cosine Transform) Column bench mark was run on the fabric. The pre-layout power consumption of the chip was 13.995mW and the post-layout power consumption was 19.979mW.
