A video processing unit (VPU) is a specialized hardware component designed to handle video processing tasks efficiently. It is optimized to perform operations such as decoding, encoding, and enhancement of video signals with minimal power consumption and latency. VPUs are commonly found in devices like smartphones, smart cameras, and media streaming devices, where video processing is essential but needs to be performed without overwhelming the main processor. The primary advantage of a VPU over general-purpose processors is its ability to process video streams more efficiently, making tasks like video decoding and real-time video enhancement faster and more energy-efficient. For instance, a VPU might be used to decode 4K video in a smartphone without causing the device to overheat or drain the battery quickly. VPUs can be built into hardware like Graphics Processing Units (GPUs), system on chips (SoCs), or integrated into other devices where high-performance video processing is required, like smart TVs or autonomous vehicles. In AI applications, VPUs are increasingly being used to accelerate tasks involving video analytics, image recognition, and real-time object tracking.
