7.1. Overview

Intel® FPGA devices support Remote System Update (RSU) feature to allow you to update the FPGA image and reconfigure the device remotely. RSU has the following advantages:

  • Provides a mechanism to deliver feature enhancements and bug fixes without recalling your products
  • Reduces time-to-market
  • Extends product life

In control block-based devices 11, you need the Remote Update Intel® FPGA IP to implement the RSU. Refer to Remote Update Intel® FPGA IP User Guide for more information.

In SDM-based devices11, you can write configuration bitstreams to the configuration flash device using RSU and Mailbox Client Intel® FPGA IP. A single configuration device can store multiple application images and a single factory image. After that, you can perform FPGA reconfiguration from the RSU image through a host. The RSU can implement JTAG-to- Avalon® Master Bridge IP, Nios® V processor, or Hard Processor System (HPS) as the RSU host.
