Anyone familiar with chip manufacturing knows that the tape-out stage is essential for ensuring the successful launch of a product. The correctness and stability of the I/O (Input/Output) interfaces are directly related to the overall performance and reliability of the chip. How can we ensure the I/O status during the tape-out phase? Let’s take a … Read more
Recently, Teledyne Technologies launched three industrial CMOS image sensors, with resolutions ranging from 1.3 million pixels to 67 million pixels, certified through the Delta space certification method and radiation testing. These industrial CMOS image sensors are designed, manufactured, and tested in Grenoble, France, and Seville, Spain, with aerospace testing screening conducted at the Grenoble facility. … Read more
Introduction FPGAs are widely used in various image processing applications, including medical and scientific imaging, space imaging, automotive, and defense fields. Regardless of the solution used, advanced algorithms may differ, but the fundamental parts are the same: they must first connect to an image sensor or camera, process the captured images, and then organize them … Read more
