5.5.1 Power Results for ADPCM Encoder Bench Mark<br />

Table 5-17 summarizes the power consumed by the chip for every stripe in the Super-CISC<br />

reconfigurable hardware fabric design when the ADPCM (Adaptive Differential Pulse Code<br />

Modulation) Encoder bench mark kernel was mapped to the fabric. The table clearly shows that<br />

parasitic annotation of the design has increased the power. The pre-layout power consumption of<br />

the chip was 5.948mW and the post-layout power consumption was 7.869mW.<br />
