We describe the design and layout of a simple 4-bit processor based on quantum dot cellular automata (QCA) using the QCADesigner design tool. The processor design is based on an accumulator architecture which reduces the required hardware complexity and allows for reasonable simulation times. Our aim is to provide evidence that QCA has potential applications in future computers provided that the underlying technology is made feasible.
