====== EP32 – 32 Bit RISC Processor for FPGA ======

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

===== ASIC Implementation =====

An [[http://users.bart.nl/users/mhx/Forth_EP32.pdf|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.

===== Code Image Example =====

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.

===== A short PowerPoint Presentation of the EP32 Target Boards =====

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 {{:projects:ep32:ep32-08-2010-ting.pdf |PowerPoint Presentation}}.\\
At the time tested on:\\
**Xilinx Virtex II - Actel ProASIC - Altera Stratix II**


===== The first Code will be for the low-cost Lattice Brevia Board =====

Its first Implementation is on the 
[[http://www.latticesemi.com/en/Products/DevelopmentBoardsAndKits/ObsoleteBoards/LatticeXP2BreviaDevKit.aspx|Lattice Brevia Board]].\\

==== Xilinx 40 Pin Zynq Board ====

One of our additional targets is the Trenz Computer Xilinx 40 Pin Zynq Board as it is the size of a 40 Pin DIP and low cost.\\
