- Description: A configurable 8b in, 8b out logic block with optional feedback
- GitHub repository
- Clock: 20000000 Hz
How it works
A programmable 8b input, 8b output freely programmable logic block with optional internal feedback. This can serve many purposes, once an FPGA-style configuration SW is available.
How to test
- Load the logic block in serial mode.
- Test the logic functionality by applying different digital inputs.
External hardware
Just a way to set digital inputs is needed, plus a way to check the digital outputs.
