Learn about the development of system emulation support for Hexagon DSP architecture in this 30-minute conference talk from KVM Forum. Explore how Hexagon DSPs, designed for energy-efficient computation and found in Snapdragon SoCs, are being integrated into upstream system emulation after having linux-user support. Discover the various functions these DSPs serve including general computation offload, audio signal processing, cellular/wifi modem operations, and sensor management. Examine the two main target use cases: Hexagon Standalone OS/Hexagon QuRT and Linux, with live demonstrations of booting these systems and explanations of what components have been modeled. Understand the current progress in this development effort and learn about the unique technical challenges presented by the hexagon DSP subsystem design, including architectural considerations that differentiate it from traditional processor emulation approaches.
