This paper introduces a hardware - soft- ware co-design of a Cellular Nonlinear Network (CNN) emulator. The Cellular Nonlinear Network is an two- dimensional array of locally coupled Nonlinear Processing Elements (NPEs). The network is used to observe evolution of spatio-temporal waves such as autowaves, travelling waves and spiral waves. The software part of the design controls the custom NPEs which are the hardware part of the design. In order to reach high performance, the software part provides control exibility on hardware part which is vital for developing and executing active wave based computing algorithms. The system has been implemented on Xilinx Spartan 3E1600E FPGA with Microblaze soft core processor using Embedded Development Kit (EDK) design tools.
