Shortwave infrared (SWIR) in machine vision imaging and other technologies – Part 1

This blog series explores the fundamentals and diverse applications of Short-Wave Infrared (SWIR) imaging, highlighting its critical role in industries such as agriculture, food production, pharmaceuticals, electronics, and space exploration, where it enables advanced material analysis, quality control, and remote sensing by leveraging unique spectral characteristics invisible to the human eye.

Exploring VDMA and Implementing Loop Testing on the PYNQ Z2 FPGA Platform

In our previous blog post, we explored the development and implementation of a Sobel filter IP core on the PYNQ Z2 FPGA. There we explained how to design the filter in Vitis HLS, export and integrate the IP (Intellectual Property) core into Vivado, and finally control the Sobel Filter using Direct Access Memory (DMA) in the PYNQ environment. In this post, we will be using a different approach called Video Direct Memory Access (VDMA). It is similar to the DMA, but designed for video applications.
