LispmFPGA

The goal of this project is to create a small Lisp-Machine in an FPGA.

• The hardware will be defined in the Verilog language on a Spartan 3 Xilinx FPGA
• The concrete system I am working with is the Spartan 3 Starter Kit from Digilent
• The core of the project is designing a CPU with Lisp optimized instruction set together with a complete set of system software written in Lisp
• The CPU is mostly ready as synthesizable Verilog
• Currently an interpreter for Lisp in Lisp is mostly ready, a compiler (prototype) is operational
• A simple garbage collector (stop and copy) is ready
• A basic OS has to be be written
• A simulator for the CPU exists on a instruction level in Common Lisp
• Currently I use Lispworks' free Lispworks Personal IDE for Lisp development

Contact

If you are interested in this project, you are invited to send me a mail at
juergen.boehm@aviduratas.de.

Wishlist

At the moment I could really need help from someone who would solder an SD/MMC card interface for the Spartan Board.

If you find the project interesting, but the documentation insufficient, please send me an e-mail. I will take this as an occasion to write one.
