Embedded system devices have emerged as sophisticated and complicated network systems. The major challenges in this research are to utilize the Ethernet frame addressing, synchronize multi-speed modules, maintaining the configuration flexibility and memory management. The design using Verilog HDL and FPGA chips can contribute to low power Ethernet Embedded Systems. Such devices can support generic low cost – network cable powered devices (e.g. network cameras, network sound system, plant network sensors, wireless network vehicles, etc.).
Recent and Current Research
VLSI Chip Design
VLSI chips design such as Low Power Direct Connect Device (DCD) core which can eliminates the operating system processing using general purpose processors to process network protocol stacks and the design of System-on-Chip (SoC) devices such as Firewire Video Stream Receiver and Transmitter that can multicast video stream by converting Firewire video stream to Ethernet traffic at the hardware level.
Wideband Embedded Media Access Controller (WEMAC)
Principal Investigator(s): Ghulam M. Chaudhry, Ph.D.
Funded by: UM Research Board, $ 27,600
Goal: WEMAC interfaces to provide substantial speedup for network applications that eliminate the need of a computer to connect any digital device to a Local Area Network (LAN). It guarantees data traffic by controlling data packets. It can transfers data from the Ethernet LAN to various fast user connectors, like the standard IEEE -1394. The prototype validates the performance improvements, low cost and power.
Publications include numerous articles on Computer Arithmetic Circuit Design, Optical Network Switches and a recent chapter “FPGA Based Video Streaming System for Bi-Network Multicasting Protocols” in the book titled:Electronic Data Streaming: Management, Processing and Transmission, Nova Publications, 2010.
