Research & Projects

2012.3–present: EPEE: An Efficient PCIe Communication Library with Easy-host-integration Property

for FPGA Accelerators.

PCIe communication library plays an important role in the integration of FPGA accelerators and computer systems as FPGA has becoming a promising accelerator platform due to its excellent parallel performance.

Software side: I designed and implemented a driver and a corresponding library. The driver runs in Linux kernel mode, which controls the hardware; the library is a wrapper for the driver, which provides user friendly APIs.

Hardware side: I implemented a PCIe endpoint with DMA and interrupt using an Xilinx FPGA, which deepened my understanding of the hardware and software co-design.

2012.9–present: GRT: A Legacy Compatible High Processing Capacity Software Defined Radio Platform.

GRT platform is a high performance, easy to use and GNU-Radio Compatible software defined radio platform. I designed and implemented GRT’s wireless NIC (network interface card) driver, which implements part of the MAC layer of 802.11 protocol. With this driver, GRT can act as a wireless NIC in Linux.
