  • Apr 2012 - Aug 2018

  2015 – 2018 Project engineer for a OneWeb LEO satellite constellation simulator for user terminal testing• Python and web page based controller application to manage embedded processing units. Hosted on a CentOS Linux server.• Embedded Linux FPGA development cards hosting RF, and digital processing functions to simulate satellite motion (dynamic delay, Doppler, SNR, and handover). Cards housed in a Vadatech high speed 40G Ethernet chassis2012 – 2015 Software lead for a small group of researchers investigating various embedded software topics• Added support for a Snapdragon SoC to the OpenOCD open source debugger. This allows users of third party development boards (e.g. Inforce IFC6410) to re-flash the boot images using off the shelf JTAG dongles and OpenOCD.• Research into compiler optimizations for E2 processor architecture. Use of a custom designed Instruction Set Simulator to analyze the performance of compiler generated assembly code and hand generated code to help drive compiler optimizations.• Real-time trace processing on Qualcomm DSP (Hexagon). Use of a Lauterbach high-speed instruction trace unit to stream trace data to a server, which generates code coverage and performance data all in real time. Platform was used to gauge effectiveness of security fuzz testing.• Embedded USB debugger. Developed a simulation platform using a Cypress embedded USB development board for a custom USB to JTAG / SWD bridge. Modified OpenOCD and gdb for use as the debugger.• Optimized the Hexagon Instruction Set Simulator using Dynamic Binary Translation based on LLVM components. Hosted on a Windows platform in either standalone mode or integrated into a SystemC TLM-2.0 platform. Show less
