(May 16, 2023) Semiconductor Engineering - Even low-cost SoCs for mobile phones today have CPUs for running Android, complex GPUs to paint the display screen, audio DSPs for offloading audio playback in a low-power mode, video DSPs paired with NPUs in the camera subsystem to improve image capture (stabilization, filters, enhancement), baseband DSPs — often with attached NPUs — for high speed communications channel processing in the Wi-Fi and 5G subsystems, sensor hub fusion DSPs, and even power-management processors that maximize battery life.
