A General Purpose, Highly Efficient Communication Controller Architecture for Hardware Acceleration Platforms

Although researchers have presented individual techniques to efficiently utilize the Peripheral Component Interconnect (PCI) bus, their contributions fail to provide a direct path to large communication bandwidth for FPGA-based hardware accelerators. Because of the increasing use of FPGAs as application accelerators, there is a need for another, more powerful communication layer to sustain very large data transfers. This paper presents the implementation of such an infrastructure and provides the designer with a familiar, easy-to-use interface. When incorporated into existing designs, 30-fold speed improvements over off-the-shelf PCI cores from Xilinx have been demonstrated.
