Notes:
1.
The typical power values are derived for a device running under the following conditions.
Four cores running at 1 GHz, Core voltage at 1V, 75% utilization (50% control/50% DSP).
A single 64 bit DDR3 running at 800 MHz, 50% utilization (50% reads/50% writes).
M3 Memory 50% utilized, PCI Express controller disabled, TDM enabled 20% loading, Serial RapidIO controller
disabled, 1 RGMII at 1 Gbps 50% loading.
A junction temperature of 60°C.
