OVERVIEW

Most of my experience has been in the area of microprocessor systems development, imbedded controller applications, and digital systems both in the hardware design and the firmware/software development.

I have thirty years designing systems using Motorola, Intel, Zilog, Fairchild, T.I., PIC, and ARM family of processors and have developed assembly language programs for all of them. I have developed programs in the higher level languages of Pascal, Basic, C and C++; and I have experience in programming in Fortran and Lisp.

I have six years experience in writing drivers, RTOS, and test functions for the embedded systems I have designed using C and C++. I have also written GUI’s using Visual C++ and Microsoft Foundation Class.

I have twenty years of experience designing complex high-speed combinatorial logic and complex state machines in FPGA's and PLD’s using the XILINX, ALTERA, and INTEL systems and I am a licensed XILINX developer. I have developed FPGA’s using schematic capture and VHDL and have simulated all of my designs using the Xilinx, Altera, or FPGA Express development systems. My designs included complex state machines, serial data converters, video synch circuits, etc.

I have designed analog amplifiers, Op-Amp circuits, feedback circuits, A/D and D/A interfaces, GPS, RS-232/245 interfaces, PCI bus interfaces, SPI Bus, I2C Bus interfaces, and MOSFET power and switching circuits.

I was responsible for doing the board layout on all of the systems that I have designed.

While designing military projects I have done thermal and failure analysis on my designs per MIL-SPEC.

I have held a management position supervising engineers, technicians and support people at Pathcor, Wavephore Inc, and Philips Semiconductor Inc. I have done labor and cost analysis, pert charts, etc., for the projects that I was directly involved in for fifteen years. I have designed using ViewLogic, Protel, Orcad, and Mentor Graphics and have developed library parts for all of them including setting up the Mentor libraries at Philips and the Orcad libraries at Pathcor.
