The 32 Bit EP32 Processor for FPGA may be combined with eForth. The kit of both is offered by Ting.
You may order the full VHDL plus eForth and documentation for print from Ting directly; the cost is $25.
You can read quite a bit of description in Tings EP32 ebook already and see the contents when you LOOK INSIDE at amazon, just click above the picture there.

An ASIC Implementation seems to have been done – we are waiting for an official confirmation statement
And google might reveal some more activities about Chen-Hanson Ting’s VHDL code.
The Code Image Example ready to Program the Brevia Board will be added as soon as available. This will set up the FPGA and as well program in the eForth software. After Flashing it in, just open your favourite Terminal Program and you can start programming in eForth via the same USB cable – no extra hardware.
Ting’s VHDL can be easily adapted to run on many FPGAs. As well it is a good project to compare different FPGA families and suppliers for performance and power consumption. Here is his PowerPoint Presentation.
At the time tested on:
Xilinx Virtex II - Actel ProASIC - Altera Stratix II
Its first Implementation is on the
Lattice Brevia Board.
