Overview

Silicon Library (SLI) DisplayPort (DP) 1.4a / Embedded DisplayPort (eDP) 1.4b TX IP cores provide a comprehensive transmitter solution compliant with VESA DisplayPort 1.4a and Embedded DisplayPort (eDP) 1.4b standards, enabling seamless integration into SoCs for modern multimedia applications. The solution consists of two modules: a physical layer (PHY) and a controller (Link Layer / PCS). The PHY is a hard macro supporting high-speed data rates up to 8.1Gbps (HBR3), while the controller is provided as a synthesizable soft macro. In addition to required DisplayPort functionalities, the solution supports optional features including Multi-Stream Transport (MST), Display Stream Compression (DSC), Forward Error Correction (FEC) and HDCP 1.4/2.3 Content Protections by its configurable controller. SLI’s PHY IPs and Controller IPs work together to deliver the best results with simplified integration although SLI’s PHY and Controller IPs can be offered as independent products .

This PHY IP is available as Silicon proven ‘off-the-shelf’ IP in various major fabs and technology nodes from 12nm to 55nm.

VESA Adaptive-Sync V2 Operation in DisplayPort VIP

In a computer system, both the GPU as well as the monitor have a certain rate at which they render or update an image, respectively. The rate is nothing but the frequency at which the image is refreshed (updated in the image it shows/displays), usually expressed in hertz, and can vary based on the content displayed on the screen.

DisplayPort 2025: Navigating the Next Wave of Display Innovation

This article breaks down the latest DisplayPort trends, the key technological shifts driving the protocol forward, and the strategic challenges implementers need to navigate — especially as DisplayPort IP finds its way into increasingly safety-critical domains.

Audio Transport in DisplayPort VIP

DisplayPort uses Secondary Data Packets (SDPs), which are transported over the Main-Link that are not main video stream data. This allows it to carry audio and video simultaneously. The VIP supports audio transmission both in the original mode as defined in the specification as well as just as any other SDP being transmitted.
