Designers often want to minimize the amount of time it takes to load a partial bitstream over a PCI Express® interface. For high-speed or time-sensitive applications that must partially reconfigure quickly, a PCIe® -based DMA can reduce load times, and it can make loading a partial bitstream up to 250 times as fast as a typical load over the embedded media configuration access port (MCAP) path. This solutions shows a simple example (based on AXI4 protocols) that can be customized and dropped into a new or existing design.
