Electronics Design Engineer

2004 - 2013

Huawei Technologies Co.

Modeled and implemented program clock reference tracking method when MPEG-2 TS packets are streamed over an IP network. Basically, it's a feasible way for FPGA to track hundreds of TV programs' time references.
Implemented video processing algorithms in FPGA. Original algorithms were written in C and had to be manually redesigned and translated into Verilog.
Supported customers to solve issues and provided system solutions. For example, the IPTV head-end project includes 600 SD channels and 100 HD channels for Etisalat UAE.

Experience

Propriety DRAM Controller for Low-cost Image Processing Platform

An FPGA-based DRAM controller that maximizes SDRAM bandwidth for image processing. The controller can be implemented in low-end FPGAs such as Intel and Altera MAX10. We verified the design by applying formal methods.

Ethernet Packet Processing Accelerator for Ultra Low Latency Application

An FPGA-based Ethernet packet processing accelerator for digital substation protection. It has ultra-low latency to meet grid protection safety standards. The accelerator was written in C and C++ and can be synthesized by Xilinx Vivado HLS and used in most Xilinx FPGAs and SoCs.

Image Sensor Bridge Interface (Patent)

https://patents.google.com/patent/US20220132075A1

An image sensor bridge interface is provided. The interface is situated between an image sensor and a processor. The interface comprises an integrated circuit. The integrated circuit comprises a Field-Programmable Gate Array (FPGA) decoupled from both image signals provided by the image sensor and a processor connected to the integrated circuit. The FPGA separates Ultraviolet (UV) and Infrared (IR) data values from image sensor-provided image data and embeds the UV and IR data values within the horizontal blanking, vertical blanking, and/or active video components of a video feed. The video feed is provided from the integrated circuit to the processor using a standard video interface, and the processor provides the video feed or provides UV images, IR images, and Red, Green, and Blue (RGB) images separated from the video feed to a computing core of a host device.
