PROJECTS

★ HTcNN: A hybrid-threading library for deep learning on embedded FPGA-based platforms

We are planning to develop a hybrid-threading library for Convolutional Neural Networks (CNNs) on embedded-FPGA devices. The project abstracts hardware (FPGA) accelerators with thread concepts. Hardware threads can cooperate with software threads to fully explore diverse parallelism inside CNN applications on heterogeneous MPSoC architectures. We try to provide a push button solution to automatically decide mapping decisions, provide the optimal hardware optimization trade-off considering multiple layers of CNNs and generate platform-runnable files (i.e., FPGA bitstreams, cpu executable files). I am the team leader in this project. (Status: in progress; hardware threading is done)

★ MPSeeker

An automatic design space exploration framework to suggest the potential best suited configurations for a high-level synthesis tool (Vivado HLS) considering both fine- and coarse-grained parallelism. It targets kernels (nested loops in C/C++) with large input data size (exceeding available FPGA BRAMs). The framework includes an FPGA area estimation model leveraging Gradient Boosted Machine (GBM) and an FPGA performance estimation tool (Lin-Analyzer).

★ Lin-Analyzer

A high-level performance analysis tool for FPGA-based accelerators. It mimics the behavior of Vivado HLS and predicts FPGA performance from C/C++ codes according to optimization pragmas given. It recommends the potential best suited configurations for HLS tools to generate accelerators with good quality. The framework is based on dynamic analysis.

★ Multiple-Target Tracking (MTT) System

MTT is one of the key components in the Advanced Driver Assistance Systems (ADAS). In this project, we provided an efficient hardware & software co-design solution for MTT on an FPGA-based heterogeneous System-on-Chip platform.
