I'm an ECE MS/PhD student at Computer System Lab, Cornell University.

Currently, I'm working on a few interesting projects with the following labs:

• NICS-EFC at Tsinghua University
• CSL at Cornell University
• WatCAG at the University of Waterloo

I was an intern at NOVAUTO Technology.

I worked at Intel Labs on Domain-Specific Language for Agile Design from Feburary to August 2021.

I want to make hardware designing and implementation faster and easier.

• FPGA Compiler

I worked on an automatic hard block placer RapidLayout with Prof. Nachiket Kapre at the University of Waterloo. We want to make placement for large-scale accelerators faster and easier. This project is still active as we work to bring RapidLayout more general.

• Deep Learning Tool Chain

At NICS lab and Novauto Technology, I worked on deploying neural networks on FPGAs. Specifically, this process includes network pruning, quantization and compilation. I maintain a set of tools to deploy TensorFlow, PyTorch and Caffe neural network models on Xilinx FPGA.

• Domain-Specific Languages

I am in the developer team of HeteroCL, a next-generation heterogenous DSL. HeteroCL decouples key hardware customizations from the algorithm specification, which boosts hardware developing efficiency and design portability. I developed a SystemC backend to generate ASIC design at Intel. Currently, there are many exciting projects going on around HeteroCL, including efforts for hardware verification, sparse architectures, and MLIR integration.

I maintain a personal blog website: zzzdavid.tech. Just trying to put down things I'm doing and stuff that I read or learned.
