Abstract:	Today’s heterogeneous computer systems combine CPUs, GPUs, and FPGAs with different architectures. GPUs with immense parallelization are best fitted for real-time video and signal processing. On the other hand, FPGAs are ideal for capturing and pre-processing multiple video streams. Therefore, partitioning computational tasks between these computational units and data-paths between them are very important. Close and efficient interaction of the individual components is, therefore, indispensable. With PCIe, modern computers provide a high-speed internal data network between CPU, GPU, and FPGA. However, since PCIe communication usually takes place via the CPU, this communication becomes the bottleneck in applications. This paper compares two different implementations which use PCIe without CPU intervention for an efficient FPGA-GPU co-design. The discussed implementation reaches a transfer jitter of only 4 μs and utilizes 72% of available PCIe bandwidth without any CPU interaction.
