pauloBlaze

A plain VHDL implementation of a small microprocessor fully compatible with the ISA of the well known PicoBlaze by Ken Chapman.

The focus is on portability and easy extendability. This costs some performance (as little as 4% on a Virtex 7) and more resources (up to 2.5X on a Virtex 7). Details can be found in the PauloBlaze documentation.

Getting Started

The PauloBlaze is a simple collection of VHDL files, with the top level module described in sources/pauloBlaze.vhd.

If you are using Xilinx ISE or Vivado, two projects are already set up. The ISE project includes a simple testbench running some program. The Vivado project includes the original KCPSM6 and a testbench running both processors in parallel and comparing their outputs. This is good for testing and debugging. Both testbenches can be easily added to ISE or Vivado.

With ISE

1. Clone this repository (git clone https://github.com/krabo0om/pauloBlaze.git)
2. Start ISE 14.7
3. Open the project (projects/ise14_7/)

With Vivado

git clone https://github.com/krabo0om/pauloBlaze.git
cd pauloBlaze/projects/vivado
vivado -mode batch -source create_project.tcl
vivado PauloBlaze.xpr
