DRAx infotainment SoCs – Digital cluster

Automotive instrument panels are a critical part of the ongoing digital cockpit revolution in the car. The automotive industry is in the midst of an overhaul to upgrade instrument clusters from analog to hybrid and fully reconfigurable digital solutions which enable rich content, bigger displays, and tailored display content with picture-realistic look and feel for a better driver experience.

TI’s powerful Jacinto™ DRAx automotive system-on-chip (SoC) platform offers a compelling solution for driving fully reconfigurable automotive digital cluster systems. TI’s Jacinto DRAx processor family is a scalable, robust, software and hardware compatible platform that can address safety, graphics, security and fast boot requirements of a digital cluster solution. In addition, it enables customers to design cost effective solutions for systems ranging from entry level to premium, with excellent power and thermal performance. The Jacinto DRAx heterogeneous architecture enables integration of additional features into digital cluster system including driver monitoring system, robust rear-view-camera, and content from infotainment head-unit.

Automotive Instrument Digital Cluster

Features and benefits

Scalable platform

The DRAx automotive processors share a common core platform and architecture, allowing software to be reused, as developers scale their design from entry to premium segment, to enable digital cluster solutions from 1920x720 @60fps to 2880x1080 @60fps display resolutions.

Graphics performance

The DRAx processor family's graphics and display architecture includes a 3-D GPU, 2-D GPU and a powerful display subsystem. This enables:

  • Rich 3D digital cluster graphics content and 60fps needle performance.
  • Multi-display support from 1920x720 @60fps to 2880x1080 @60fps.

Safety and security support

The DRAx automotive processors have a number of safety and security features supported in hardware that enable customers to design systems that can achieve ASIL-B safety levels. The Jacinto DRAx processor’s security support enables secure boot and run-time security.

Fast/early boot

The DRAx heterogeneous architecture and performance enables customers to meet early and fast boot requirements of cluster solutions including:

  • Early CAN response, splash screen and early audio.
  • Fast tell-tales and fast 3D graphics including gauges and needles.
