# FPGA CNN

FPGA implementation of [Cellular Neural Network](http://www.scholarpedia.org/article/Cellular_neural_network) (CNN)  
![CNN formula](https://github.com/dem123456789/FPGA-CNN/blob/master/Fomula.PNG "CNN")

## Initialization
#### CNN 
`CNN.v` is Top-level design with initialization for A, B, I template  
`SixteenbySixteen.java` generates Verilog code for 16x16 layer module [sixteenbysixteen.v](https://github.com/dem123456789/FPGA-CNN/blob/master/Quartus/sixteenbysixteen.v)
#### Default 
[CornerDetection](http://en.wikipedia.org/wiki/Corner_detection)  
Other available templates in [here](https://github.com/dem123456789/FPGA-CNN/blob/master/Template_library_v3.1.pdf)
 
## Instruction

1. Change the `size` variable in SixteenbySixteen can generate different dimension module  
2. Contain a 4x4 layer module [fourbyfour.v](https://github.com/dem123456789/FPGA-CNN/blob/master/Quartus/fourbyfour.v)  
3. fourbyfour.v and sixteenbysixteen.v use one multiplier and two adders in calculation of equation 1  
4. Any files ended with 18mul are associated with the version using 18 multipliers and finishing equation 1 calculation in one clock cycle  
5. Top level design CNN.v and CNNfourbyfour.v is shared with both versions  
6. Change the module link, for example, sixteenbysixteen u1 to sixteenbysixteen18mul u1  
will change to the version which does equation 1 calculation in one clock cycle
7. Eq1 Initial folder contains the work by Sangeetha J. who completes using one multiplier and one adder to calculate template A times output Y or template B times input U. The default version which using one multiplier and two adders in calcualtion of equation 1 is based on her contribution

#### Default 
`size = 16;`  
CNN.v is using sixteenbysixteen.v
