Les Kohn


Les Kohn is well regarded in Silicon Valley as one of the leading chip architects in the industry. Kohn combines his wealth of experience as a silicon architect with a  talent for creating innovative solutions to complex problems. 

Prior to Ambarella, Kohn was CTO and co-founder at Afara. After Afara was acquired by Sun, Kohn became a fellow at Sun and continued to develop Afara’s throughput computing technology that would become the primary focus of Sun's  UltraSPARC roadmap. 

Kohn was also chief architect at C-Cube, where he led the development of three generations of digital video CODECs, including the first single-chip MPEG-2 and  HD/multi-stream CODECs. Prior to C-Cube, Kohn was a distinguished engineer at  Sun where he was the chief architect of UltraSPARC I and II, Sun's first 64-bit  microprocessors. Before Sun, Kohn was chief architect of the Intel i860 and co-architected the National 32000 microprocessor family.



Ambarella’s products are used in a wide variety of human and computer vision applications, including video security, advanced driver assistance systems (ADAS), electronic mirror, drive recorder, driver/cabin monitoring, autonomous driving, and robotic applications. Ambarella’s low-power SoCs offer high-resolution video compression, advanced image processing, and powerful deep neural network processing to enable intelligent cameras to extract valuable data from high-resolution video streams.
