<p>The designer of an FPGA embedded processor system has complete flexibility to select any combination of peripherals and controllers. In fact, the designer can invent new, unique peripherals that can be connected directly to the processor bus. If a designer has a non-standard requirement for a peripheral set, this can be met easily with an FPGA embedded processor system. For example, a designer would not easily find an off-the-shelf processor with ten UARTs. However, in an FPGA, this configuration is very easily accomplished.</p>
