Michael Bruns is Principal Engineer and President of Cascade Stream. Previously he was a Senior Staff Software Engineer with Coherent Logix, Inc. of Austin, Texas. As technical lead for video codec development his responsibilities included hardware/software architecture, encoder algorithm development, and performance critical implementation. He also contributed to the development of Coherent Logix’s hierarchical, scalable programming model. Before joining Coherent Logix, he was a member of the core technology team of Elemental Technologies where his work included optimizations for real-time performance of high definition video encoders using a general purpose graphics processing unit (GPGPU) programming model. He was among the original engineers of Ambric, a chip manufacturer that developed a massively parallel processor array. He contributed to many aspects of Ambric’s solution in addition to video codec applications, including the programming model, software tools, and run-time host software. Prior work involved hardware and software design and system architecture for Grass Valley Group’s video server product line. Mr. Bruns holds a MSEE degree from the University of California, Berkeley and BSEE from Northwestern University. He is a member of IEEE and a resident of Portland, Oregon.
