The increased integration and personalization of the automotive cockpit is enhancing the driving experience by making interior cabin more comfortable and convenient for drivers and passengers. In this video, TI’s digital cockpit and body electronics experts discuss the evolution happening in display, audio, driver monitoring, gesturing and more that are making way for a better in-vehicle experience.

Texas Instruments Automotive Applications Featured Products: Jacinto™ DRAx

The Jacinto DRAx family of automotive digital cockpit processors (DRA7xx), paired with robust software and ecosystem offering bring unprecedented feature-rich, in-vehicle infotainment, instrument cluster and telematics features to the next generation automobiles.

1.     DRA726

Texas Instruments DRA72x processor for smart driving solutions

DRA72x ("Jacinto 6 Eco") infotainment applications processors are developed on the same architecture as Jacinto 6 devices to meet the intense processing needs of the modern infotainment-enabled automobile experiences.

DRA72x devices offer upward scalability to DRA74x devices, while being pin-compatible across the family, allowing Original-Equipment Manufacturers (OEMs) and Original-Design Manufacturers (ODMs) to quickly implement innovative connectivity technologies, speech recognition, audio streaming, and more. Jacinto 6 and Jacinto 6 Eco devices bring high processing performance through the maximum flexibility of a fully integrated mixed processor solution.

Programmability is provided by a single-core Arm Cortex-A15 RISC CPU with Neon™ extensions and a TI C66x VLIW floating-point DSP core. The Arm processor lets developers keep control functions separate from other algorithms programmed on the DSP and co-processors, thus reducing the complexity of the system software.

Additionally, TI provides a complete set of development tools for the Arm, and DSP, including C compilers and a debugging interface for visibility into source code execution.

The DRA72x Jacinto 6 Eco processor family is qualified according to the AEC-Q100 standard.

2.    DRA746

Texas Instruments DRA74x processor for smart driving solutions

DRA75x and DRA74x (Jacinto 6) infotainment applications processors are built to meet the intense processing needs of the modern infotainment-enabled automobile experiences.

The device enables Original-Equipment Manufacturers (OEMs) and Original-Design Manufacturers (ODMs) to quickly implement innovative connectivity technologies, speech recognition, audio streaming, and more. Jacinto 6 devices bring high processing performance through the maximum flexibility of a fully integrated mixed processor solution. The devices also combine programmable video processing with a highly integrated peripheral set.

Programmability is provided by dual-core Arm®Cortex®-A15 RISC CPUs with Arm® Neon™extension, TI C66x VLIW floating-point DSP core, and Vision AccelerationPac (with one or more EVEs). The Arm allows developers to keep control functions separate from other algorithms programmed on the DSP and co-processors, thus reducing the complexity of the system software.

Additionally,TI provides a complete set of development tools for the Arm, DSP, and EVE co-processor, including C compilers and a debugging interface for visibility into source code.

The DRA75x and DRA74x Jacinto 6 processor family is qualified according to the AEC-Q100 standard.

3.    DRA80M

Texas Instruments DRA80x processor for smart driving solutions

Automobiles are becoming more and more connected - both inside the car, within the various subsystems/domains as well as with the outside world, with connectivity via Bluetooth, LTE, WiFi etc.

Much more information and data are being shared or transferred between the various domains; for example, video from rear and surround view cameras for displayed in the head unit; data from the chassis is sent to the on-board diagnostic unit, etc. As the amount of data that has to be integrated and transported between the various domains in a time sensitive manner has increased, car manufacturers are looking to include a network gateway, based on Ethernet protocols, in cars. Such gateways should be able to handle multiple connectivity protocols such as CAN, CAN-FD, TCP/IP to name a few. TI’s DRA80x family of products enable automotive manufacturers to build scalable and cost optimized network gateway features in cars, thanks to its high level of integration and purpose built peripherals, such as Gigabit Ethernet MACs.

DRA80x Automotive Gateway processors are built to meet the intense processing needs of automotive gateway. The DRA80x family of devices combines four or two Arm®Cortex®-A53 cores with an ASIL-C capable dual Arm® Cortex®-R5MCU subsystem and six Gigabit Ethernet MACs in the MAIN domain and one Gigabit Ethernet MAC in the MCU domain to create an SoC capable of implementing an Automotive Gateway system with plenty of automotive connectivity and functional safety processing.

The four Courtex-A53 cores in the DRA804M are arranged in two dual-core clusters with shared L2 memory to create two processing channels to address additional safety concepts. The two Arm®Cortex®-A53 cores in the DRA802M are available in a single dual-core cluster and two single-core cluster options. Extensive ECC is included for on-chip memory and interconnects for reliability. Cryptographic acceleration and secure boot are available on some DRA80x devices, in addition to granular whitelist firewalls managed by a security controller core.

Programmability is provided by the Arm® Cortex®-A53 RISC CPUs with Arm® Neon™extension, and the dual Arm® Cortex®-R5 MCU subsystem is available for general purpose use. The Ethernet subsystem can be used to provide up to six ports of Ethernets, including TSN and Ethernet/IP, for standard Ethernet connectivity. Additionally, TI provides a complete set of development tools for the Arm® cores including C compilers and a debugging interface for visibility into source code execution. Safety documentation is available for applications needing to meet functional safety standards.
