High Speed Transaction Hardware Channel in Loosely-Coupled Reconfigurable Computing Emulation System

Abstract:

The loosely-coupled reconfigurable computing model includes the host microprocessor in conjunction with an external stand-alone reconfigurable hardware which takes advantage of low cost in technology and development time. It can work as a fast emulation approach to study reconfigurable computing prototype system. One of the key features of such emulation system is the ability to perform the communication. In this paper, we proposed a high speed hardware channel with direct memory access(DMA) transaction method based on Xilinx ML555 development kit and PCI-express(peripheral component interconnection express) endpoint block IP. Experiments show that both read and write transaction speed in this design meet the theoretical maximum speed.
