Reconsideration of Computing Paradigms and a Novel Reconfigurable Architecture

With the on-chip resources largely increased, the computing paradigm of modern architectures are much different from traditional ones. The relation between temporal computing and spatial computing is getting more and more intricate. In this paper, a coarse-grained reconfigurable architecture is proposed named as programmable dataflow computing architecture: ProDFA. With both fine-grained control ability and long-term control logic, ProDFA implements coarse-grained reconfigurability and fine-grained controllability, which brought both flexible programmability and high efficiency. A case study on block ciphers is done. A specific reconfigurable structure for block ciphers is designed and several mainstream block ciphers are mapped and evaluated. The experimental results show the high efficiency of the specific reconfigurable structure.
