Design and Evaluation of Two Asynchronous Token Ring Adapters

Lookup NU author(s): Professor Alex Yakovlev



The goal of this paper is to design and measure the performance of two speed-independent asynchronous adapters for a communication architecture with distributed arbitration. The protocol is defined on the principles similar to those of the Token Ring but attempts to exploit the asynchronous design approach in improving the operational scalability of the system. Its two versions considered in this paper reflect the trade-off between the greater functional capability and low-latency requirements. We show the power of Signal Transition Graphs in specifying, verifying and synthesizing the adapter's logic. Using timing information obtained at the implementation level, we finally estimate the performance of the token-ring architecture with point-to-point interconnection.
