Introduction

Scalable Low-Voltage Signaling with Embedded Clock (SLVS-EC) is an advanced interface standard pioneered by Sony Semiconductor Solutions Corporation (SSS) specifically designed for rapid and high-definition image sensor transmission. It streamlines the process of constructing camera setups. Equipped with an integrated clock signal, it proves beneficial for scenarios demanding expanded capacity, enhanced speed, or extended transmission ranges.

SLVS-EC expands our extensive range of Smart Embedded Vision IPs, empowering high-speed video applications tailored for intelligent-edge devices. For more detailed information, see Smart Embedded Vision page.

The technical demonstration of the PolarFire SLVS-EC Video Demo operates seamlessly with the PolarFire video kit, SLVS-EC FMC device and an HDMI monitor. This document serves as a comprehensive guide to facilitate the execution of the demo. The design of the demo represents a fully integrated solution crafted using Microchip's Libero® SoC Design Suite.

This document describes the PolarFire SLVS-EC Video Demo, demonstrating integration with the PolarFire video kit and providing detailed instructions. The demo showcases the following functions:
  1. Supports 4K video capture over SLVS-EC FMC camera and cropped to 1080p60 video output over HDMI 2.0.
  2. Implements Image Signal Processing (ISP) pipeline on a raw video data.
  3. Provides GUI-based image parameter controls.
  4. Supports the Auto Exposure Control.
The SLVS-EC Receiver IP core offers an SLVS-EC interface for PolarFire® FPGA, is a compact receiver IP that adheres to the SLVS-EC V2.0 standards. By combining this IP with FPGA's high-speed transceiver, this IP facilitates the extraction of pixel clock and data through the high-speed serial embedded clock/data from the image sensor. This IP core supports configurations of two, four, and eight lanes, with speeds up to 4.752 Gbps per lane, and data types of Raw 8, Raw 10, and Raw 12 formats. Additionally, the SLVS-EC Rx IP core supports three Baud Rates, as listed in the following table.
