Mean filtering is a fundamental digital signal processing technique commonly used for image and signal denoising. This article will detail how to implement a simple yet efficient mean filter using the Verilog hardware description language. Basic Principles of Mean Filtering The core idea of mean filtering is to replace the value of a pixel with … Read more

Source: EETOP BBS Author: eebinqiu Original: http://bbs.eetop.cn/thread-628991-1-1.html This was first written in 2011, initially supporting only 640×480 resolution on the Cyclone4 E40, without implementing a deblocking filter, and the frame rate was only 25fps. Recently, I took on a project for an H.264 FPGA decoder for drones, which required implementing 720p at 60fps with a … Read more
Introduction — In FPGA-based image acquisition and display systems, large-capacity and high-speed memory is often required. Among various random access memory devices, SDRAM is an ideal choice due to its low cost, small size, high speed, and large capacity. However, the control logic of SDRAM is quite complex, and the timing requirements are very strict, … Read more
In FPGA design, frequency division is often required. For even frequency division, the code is relatively simple; the clock is inverted when the counter reaches half of the division factor, thus completing the even frequency division.For odd frequency division, the approach is slightly more complex. First, two temporary frequency division variables need to be defined: … Read more
Word count: 1092, reading time approximately 6 minutes Continuing from the last session, today we will implement the functionality of UART, primarily using the hardware description language Verilog. The interface design is actually quite simple. If we distill its essence, it can be divided into three main parts: data acquisition, state machine, and interface timing. … Read more
