How to Implement Image Processing Algorithms in FPGA Hardware

Lance Harvie December 17, 2023

Recognized for their parallelism and reconfigurability, FPGAs prove ideal for real-time processing in medical imaging and computer vision. The step-by-step approach starts with understanding FPGA basics, emphasizing their reconfigurable nature and parallel processing. It guides users in algorithm selection based on factors like processing speed, resource utilization, and adaptability, then highlights designing modular and scalable algorithms. The process includes simulation for verification, synthesis using tools like Xilinx Vivado and Intel Quartus Prime, interfacing with image sensors, and testing on real hardware. The conclusion underscores FPGA's advantages in image processing, presenting ongoing opportunities for innovation in diverse industries.


What does it mean to be 'Turing complete'?

Nathan Jones October 16, 20235 comments

The term "Turing complete" describes all computers and even some things we don't expect to be as powerful as a typical computer. In this article, I describe what it means and discuss the implications of Turing completeness on projects that need just a little more power, on alternative processor designs, and even security.


Square root in fixed point VHDL

Jari Honkanen October 10, 2023

In this blog we will design and implement a fixed point square root function in VHDL. The algorithm is based on the recursive Newton Raphson inverse square root algorithm and the implementation offers parametrizable pipeline depth, word length and the algorithm is built with VHDL records and procedures for easy use.


Mastering Modern FPGA Skills for Engineers

Lance Harvie October 5, 2023

In the rapidly evolving tech industry, engineers must acquire proficiency in modern FPGA skills. These skills empower engineers to optimize designs, minimize resource usage, and efficiently address FPGA design challenges while ensuring functionality, security, and compliance.


FPGA skills for the modern world

GLENN Kirilow September 4, 2023

With the ever increasing number of applications involving video processing, AI or edge computing the appetite for suitably skilled FPGA Engineers has never been higher from the market which is expected to grow to $15 billion USD by 2027!

In terms of industries opportunities can be typically found within:

  • Automotive
  • Aerospace
  • Defense
  • Data Processing

However this list is certainly not exhaustive as any application requiring algorithms which can leverage from highly parallel and...


Three more things you need to know when transitioning from MCUs to FPGAs

Duane Benson August 24, 20231 comment

Take a look at three more important difference between FPGAs and MCUs: "code reuse" vs templating, metastability and blocking vs. non-blocking operations.


Jumping from MCUs to FPGAs - 5 things you need to know

Duane Benson July 31, 2023

Are you a microcontroller expert beckoned by the siren song of the FPGA? Not long ago, that was me. FPGA-expert friends of mine regularly extolled the virtues of these mysterious components and I wanted in. When I made the leap, I found a world seemingly very familiar, but in reality, vastly different. I found that my years of C programming and microcontroller use often gave pre preconceived interpretations of FPGA resource material which resulted in eye-roll class mistakes in my code. I’ve gleaned five things of vital importance to help you make that transition faster than I did.


Fit Sixteen (or more) Asynchronous Serial Receivers into the Area of a Standard UART Receiver

Michael Morris March 29, 20155 comments
Introduction

This article will describe a technique, available in many current FPGA architectures, to fit a large amount of logic into a small area. About ten years ago now (Feb/Mar 2005), I helped develop a multi-line Caller ID product. The Multi-Channel Asynchronous Receiver (MCAR) FPGA core developed for that product will be used to illustrate the technique(s) needed to fit a 16 channel MCAR into a single Spartan II XC2S30-5VQ100 FPGA.

To stay true to the original design, I...


Use Microprogramming to Save Resources and Increase Functionality

Michael Morris March 21, 2015
Introduction

Microprogramming is a design approach that every FPGA designer should have in their bag of tricks. I subscribe to the concept that microprogramming is a structured approach to the design of state machines. This is essentially the view of Maurice Wilkes when he first proposed microprogramming in 1951 as an alternative method for the implementation of the control section of a computer. Wilkes was interested in improving the reliability and reducing time needed to implement...


How FPGAs work, and why you'll buy one

Yossi Kreinin June 20, 201315 comments

Today, pretty much everyone has a CPU, a DSP and a GPU, buried somewhere in their PC, phone, car, etc. Most don't know or care that they bought any of these, but they did.

Will everyone, at some future point, also buy an FPGA? The market size of FPGAs today is about 1% of the annual global semiconductor sales (~$3B vs ~$300B). Will FPGA eventually...

Designing Embedded System with FPGA - 1

Pragnesh Patel October 28, 200711 comments

With the introduction of soft processors and related tools (like EDK from Xilinx), implementation of basic embedded system in FPGA is made easy. This requires very little or almost no knowledge of VHDL programming. Actually that’s how I started. If user is interested in taking full advantage of FPGA and its parallel processing power, then yes, detail understanding of soft processor, its peripheral bus and VHDL programming is required.

 

I will start with...

Designing Embedded Systems with FPGA-2

Pragnesh Patel November 13, 200710 comments

In last part, we created hardware design of basic system. The next step is to generate (compile) hardware design. Compiled hardware design is known as bit-stream andstored in *.bit file. To compile hardware, use hardware->generate hardware tab. The complete hardware design generation takes several seconds to several minutes depending on computer speed and design complexity. In back ground, the whole design process involves many different steps including synthesis, placement, routing and...
