Circuit boards with Field Programmable Gate Arrays (FPGAs) have a historically diverse set of standards for communicating with other devices. This provides a challenge for developers creating FPGA applications and makes migration of applications from one board or FPGA to another difficult. Many board manufacturers, including Xilinx and GiDEL, create boards with Peripheral Component Interconnect Express (PCIe) buses. PCIe provides a low-level standard for transferring data between a Central Processing Unit (CPU) and an FPGA, and these manufacturers have designed Direct Memory Access (DMA) engines to implement the standard. However, each manufacturer’s DMA engines do not share a standard interface, leading to the same difficulties switching between boards or FPGAs. The goal of this project is to reach a common interface for the diverse set of available DMA engines to improve application development productivity, particularly for the Autopipe environment, an environment for developing multi-device streaming applications.
