Features and benefits

Performance provided by heterogeneous architecture

The Jacinto DRAx automotive processors support multiple digital cockpit applications, including those with safety requirements, without compromising performance. In addition to the main Arm® Cortex®-A15 core, 3D Graphical Processing Unit and multimedia accelerators enable multiple use cases and functionalities such as:

  • In-vehicle infotainment
  • Digital instrument cluster
  • Multi-OS/Multi-domain
  • Navigation and routing
  • Voice recognition and control
  • Smartphone projection
  • High-performance graphics and display
  • Fast boot/early boot
  • Safety certifiable systems
  • Hardware and software security

Software platforming

The Jacinto DRAx automotive processors share a common core platform and architecture, allowing software to be reused, as developers scale their design from entry to premium segments thereby reducing the time to market.

Integration of automotive peripherals to optimize system BOM

The Jacinto DRAx automotive processors provide the right set of peripherals to enable digital cockpit integration and optimized system BOM including:

  • Multi-HD display support
  • Multi-HD camera input interfaces
  • Automotive peripherals including eAVB, CAN and MOST
  • Rich set of high-speed and connectivity interfaces including PCIe, USB, etc.

Signal, image and vision processing

The Jacinto DRAx automotive processors integrate digital signal processor (C66x DSP), image signal processor (ISP) and embedded vision engine (EVE) co-processors to offload all the heavy signal, image and vision processing to enable integration of following cockpit features:

  • Software-defined digital radio
  • Audio processing
  • Driver monitoring and identification
  • Robust rear-view camera and surround view
  • Image processing
