Berger Code-Based Concurrent Error Detection in Asynchronous Burst-Mode Machines
Sobeeh Almukhaizim, Yiorgos Makris · 2006
We discuss the use of the Berger code for concurrent error detection (CED) in asynchronous burst-mode machines (ABMMs). We present a state encoding method which guarantees the existence of the two key components for Berger-encoding an ABMM, namely an inverter-free ABMM implementation of the circuit and an ABMM implementation of the corresponding Berger code generator. We also propose improved solutions to two inherent problems of CED in ABMMs, namely checking synchronization and detection of error-induced hazards. Experimental results demonstrate that Berger code-based CED reduces significantly the cost of previous CED methods for ABMMs
