As I drive throughthe vineyard-covered hills of San Luis Obispo, Calif., the tiny Global Positioning System receiver in my phone works with Google Maps to alert me to upcoming turns. The app reassures me that I'll arrive at my destination on time, in spite of a short delay for construction.

How different this trip would have been in the pre-GPS era, when the obscured road sign at one intersection would likely have sent me off track. I have a weak sense of direction, and getting lost—or worrying about getting lost—was a stressful part of my life for a long time.

Deep learning is a critical computing approach that is pushing the boundaries of technology – crunching immense amounts of data and uncovering subtle patterns that humans could never discern on their own. But for optimal performance, deep learning algorithms need to be supported with the right software compiler and hardware combinations. In particular, reconfigurable processors, which allow for flexible use of hardware resources for computing as needed, are key.

For more than 25 years, Rory Cooper has been developing technology to improve the lives of people with disabilities.

Cooper began his work after a spinal cord injury in 1980 left him paralyzed from the waist down. First he modified the back brace he was required to wear. He then turned to building a better wheelchair and came up with an electric-powered version that helped its user stand up. He eventually discovered biomedical engineering and was inspired to focus his career on developing assistive technology. His inventions have helped countless wheelchair users get around with more ease and comfort.
