Developed software for Marconi's fiber-to-the-home product. * Modified the pSOS board support package for an existing card to be used with the new home interface card.* Designed and implemented flash memory drivers and manager, and an application-level flash memory access C++ class to support storing and loading multiple software and FPGA images. The new design sped up development by significantly reducing the time needed to download new images.* Designed and implemented drivers, including the interrupt service routines to handle alarm conditions, and application-level access C++ classes to control two FPGAs. I also wrote test software used by the hardware engineers to evaluate FPGA operation.

Cedar Rapids, Iowa, Us

Developed software for the Air Force 1 communications switch which uses multiple, redundant processor pairs, networked together, to provide highly reliable, clear and secure, audio and data switching, and to control the communication devices, such as telephones, landlines, radios, and cryptos, connected to the switch.* Designed and implemented software to validate operator-selected connection requests and to convert these requests into commands to the switching hardware, using a commercial database to define valid connections and to generate source code tables for validating operator requests.* Designed and implemented software to control the switching of audio, data, and control signals between the communication devices.* Integrated the switch software with the custom hardware, and integrated the hardware and software components into the switching system.* Created a tool for analyzing system activity logs to support resolving customer-reported problems.* Provided direction to other software engineers assigned to the project, and interacted extensively with customer personnel.Developed software for a German navy digital communication switch, using multiple nodes, each containing a Windows NT workstation and TI DSPs housed in a VME chassis, connected by E1 links to provide distributed audio and data switching.* Designed and implemented complex switching control software.* Provided direction to other software engineers assigned to the project.Developed software for a special-purpose PBX, using multiple TI DSP processors connected via T1 links to collect audio and distribute it throughout the system.* Designed and implemented a simple run-to-completion executive.* Designed and implemented device drivers for the T1 links and A/D–D/A converters.
