Some Xilinx device families contain high-performance PowerPC microprocessor embedded blocks.
For power estimation, these blocks are represented in a separate sheet within XPE. Details for each PowerPC setting are available in the applicable device User Guide. Typically, you can provide the processor main clock frequency along with details of the processor local bus, memory, and eventual DMA controllers. The following figure presents an example with a Virtex-5 device.
