How to get the current timestamp First use std::chrono to get the current system time, then convert the current system time to the epoch time std::time_t type, and then use std::localtimeConvert the std::time_t type to the local time structure std::tm type, and finally use strftime to format the time output. The std::tm structure contains a […]

Implementing PWM breathing light on Youjing Technology DE10-Nano
1. What is a breathing lamp The so-called breathing light means that the light can change from dark to bright rhythmically like human breathing. We see this kind of visual effect in many places, such as home decoration lighting, smartphone call reminders, etc. 2. What is PWM The full name of PWM is Pulse Width […]

Optimization and deployment of parallel image filtering algorithm based on Jetson Nano
Optimization of parallel image filtering algorithm based on Jetson Nano We implemented convolution algorithms based on GPU (CUDA) and CPU (PThread). On this basis, we further implemented Sobel, Laplacian, mean and Gaussian filters, which can be used for image processing. A typical application scenario It’s image noise reduction. Therefore, our experiments mainly focus on the […]
