PDP-8 Minicomputer

It's 40 year old technology, but it still pretty cool and complex. I'm working to realize the PDP-8 minicomputer from the early 70s using an FPGA. Stay tuned for progress updates!

Parallel Adder / Multiplier using VHDL

I designed a state machine controller using VHDL. This state machine implemented a parallel adder and multiplier with overflow capability. This project used the Nexys2 board from Digilent. I used Xilinx ISE for the coding and Modelsim for the simulation. For a full report see "Adder / Multiplier in VHDL" under papers.
