AN69211 explains how to use Cypress high-density programmable FIFOs in video and imaging applications and the benefits offered over conventional FPGA and DDR SDRAM solutions. This information is intended for engineers who work on video and imaging applications and are familiar with FPGA and video standards.

Introduction

Video frame storage and synchronization are a part of almost any video and imaging application. Because the nature of video data is sequential, high-density FIFOs (HDFIFOs) are best suited for these applications.

This application note describes a few video applications to explain the data path and data handling required. It also compares implementing a frame buffer using Cypress HDFIFO (CY7FXXXX) to the conventional method of using an FPGA and DDR SDRAM, along with memory size and bandwidth calculations. Advantages of using Cypress HDFIFO over the conventional solution are described.
