Design of clock-free asynchronous systems for real-time signal processing

The authors describe a clock-free design approach that facilitates modular design without compromising global performance. The goal is to support rapid prototyping of real-time digital signal processing systems with a minimum amount of design effort. The approach allows the scaling up of small prototype systems to very large multiboard systems without concern for global timing problems. The authors address the interconnect schemes applicable to real-time systems and the circuit design techniques for a clock-free implementation
