Description
Kuchen is an experimental FPGA-based computer designed for timeless applications.
Note: While all functionality has been tested separately, it has not been tested simultaneously. Due to the limited amount of available logic it may or may not be possible to simultaneously use all functionality in a useful manner. We have created a bounty challenge to encourage the development of such a demonstration.
