This paper describes the realization of an interconnect Delay Insensitive (DI) FPGA architecture with distributed asynchronous control. This architecture maintains the basic block structure of traditional FPGAs allowing the potential use of existing FPGA design tools in block design. This asynchronous FPGA architecture is mainly aimed at tolerating the unpredictable delay variations caused by process...
Interconnection networks with adaptive routing are susceptible to deadlock, which could lead to performance degradation or system failure. Detecting deadlocks at run-time is challenging because of their highly distributed characteristics. In this paper, we present a deadlock detection method that utilizes run-time Transitive Closure (TC) computation to discover the existence of deadlock-equivalence...
Asynchronous techniques have become more significant with continued scaling of VLSI technologies. This paper proposes an asynchronous FPGA architecture. Different from previous methods of introducing asynchrony into FPGAs, our method seeks to preserve the current FPGA cell structure as much as possible, whilst achieving delay insensitivity in the inter-cell interconnects. By using David Cells as the...
