Hardware/Firmware Interface Design

Gary Stringham is the founder and president of Gary Stringham & Associates, LLC. He has 30+ years of experience in the embedded systems industry, assisting clients in their product development and engineering training. He has extensive expertise in diagnosing and resolving a broad range of engineering problems, including: helping litigation clients understand technical aspects of case; working on the design, implementation, and testing of solutions involving software, hardware, and firmware. Gary previously worked for Hewlett-Packard Company, where he developed and maintained several device drivers controlling a variety of blocks on various ASICs and SoCs for HP LaserJet printers. This involved diagnosing chip problems when they occurred and designing and developing firmware workarounds. Gary helped develop various tools used for the development, testing, and manufacturing of HP-UX workstation and LaserJet printer products. For a printer emulator tool, he developed the board design, the FPGA code, the firmware running on the tool, and the software running on the host computer. In one instance, the emulator reduced a 40-hour manual test to a 35-minute automated test. For a manufacturing test tool, he architected the tool, led a team of 10 engineers to develop it, and deployed it at five manufacturing sites world-wide. Gary is a Senior Member of IEEE. He holds a BSEE from Brigham Young University and an MSEE from Utah State University.
