This is based upon the Papilio One 500K development board from Gadget Factory and the ZPUino soft-processor. Processing blocks are to be written in VHDL and compatible with the OpenCores Wishbone architecture for portability and easy integration with the ZPUino.
I chose the Papilio One because it's a good, relatively inexpensive starter board. I chose the ZPUino because it's open source, can be built using the free Zilinx tools (which also work well with the Papilio). Also, it's integrated with the DesignLab development environment , which provides a familiar development platform.
