An Asynchronous Communication Mechanism Using Self-timed Circuits

Lookup NU author(s): Dr Fei Xia, Professor Alex Yakovlev, Dr Alex Bystrov, Dr Albert Koelmans, Professor David Kinniment, Dr Delong Shang



An asynchronous data communication mechanism (ACM) using self-timed circuits is presented. Mutual exclusion elements are used to concentrate potential metastability to two discrete points so that it can be resolved entirely within the mechanism itself. Self-timed circuits allow the minimisation of the interface between the reader and writer processes and the mechanism. Initial analysis shows that this VLSI solution is more robust with regard to steering logic metastability, and can potentially run faster than similar solutions under fundamental mode assumptions. It is therefore more suitable for use in on-chip multi-processing systems.
