DeepStream is an AI-based video analytics platform developed by NVIDIA that allows developers to create complex video processing pipelines, including tasks like object detection, classification, and tracking. Jetson Nano is one of NVIDIA's popular edge computing devices that provides high-performance computing power to run DeepStream pipelines.
In addition to the powerful performance of Jetson Nano, DeepStream Boost is an enhancement that provides hardware acceleration for certain AI tasks by leveraging specialized computing components such as Tensor Cores. This results in significantly improved performance and efficiency of the DeepStream pipeline.
One critical aspect of developing DeepStream applications is timing accuracy. Video processing pipelines must be able to process a certain number of frames per second (FPS) without any delay, jitter, or dropped frames. This is particularly important for real-time applications such as security monitoring, autonomous vehicles, and robotics.
To achieve high timing accuracy, Jetson Nano provides hardware-based clocks that can be used to synchronize the data flow and execution of DeepStream pipelines. These clocks include PTP (Precision Time Protocol), TSC (Time-Stamp Counter), and PWM (Pulse-Width Modulation).
PTP is a protocol used for clock synchronization in distributed systems, typically in conjunction with Ethernet networks. It provides sub-microsecond time accuracy and can synchronize clocks across multiple devices.
TSC is a CPU register that increments at a fixed rate, providing a high-resolution timestamp for each instruction executed by the CPU. This timestamp can be used to synchronize the data flow and execution of different threads or components of a DeepStream pipeline.
PWM is a signal generated by the Jetson Nano's CPU that can be used to control external devices, such as cameras, actuators, or sensors. By synchronizing the PWM signal with the TSC timestamp, DeepStream pipelines can be tightly coupled with external actuators, ensuring that the response time of the system is minimal.
In conclusion, leveraging the hardware-based clocks provided by Jetson Nano and utilizing DeepStream Boost can result in highly performant and accurate video analytics applications. It is essential to understand the capabilities and limitations of these clocks and tune the DeepStream pipeline accordingly to achieve optimal performance.
