The top level of the hardware design is a Xilinx ISE Project Navigator Project (.XISE) for
Xilinx ISE version 13.4. The Verilog-based HDL design instantiates the MicroBlaze core,
the support hardware required to run the MicroBlaze, and the peripherals that interface
to the Pmod ports. This is supplied as a Xilinx software development kit (SDK) project
which includes a demonstration software application to evaluate the Sonoma subsystem
reference design. The lower level c-code driver routines are portable to the user’s own
software project.
