  • TI has launched an auto processor family called Jacinto
  • The devices execute ADAS operations using the power of up to 20 W

Advanced driver-assistance systems (ADAS) are electronic systems that help the vehicle driver while driving or during parking. When designed with a safe human-machine interface, they are intended to increase car safety and road safety. ADAS systems use electronic technology such as microcontroller units (MCU), electronic control units (ECU), and power semiconductor devices. As it uses microcontroller systems, the accuracy and decision-making capability of the system depends upon the speed and robustness of the processor.

Texas Instruments(TI) has introduced a new platform called Jacinto. Jacinto complies of two devices in the platform. TDA4VM processors are made for ADAS applications whereas the DRA829V processors are made for gateway systems. It includes specialized on-chip accelerators to segment and assists data-intensive tasks. A common example of such tasks is computer vision and deep learning.

According to TI, TDA4VM and DRA829V processors incorporate functional safety microcontrollers. It helps original equipment manufacturers (OEMs) and Tier-1 suppliers to support both ASIL-D safety-critical tasks and convenience features in a single chip.

Both devices share a single software platform. It reduces system complexity and cost. It does so by enabling developers to reuse their software investment across multiple vehicle domains. The devices execute ADAS operations using the power of up to 20 W. It eliminates the need for active cooling.

The TDA4VM processor offers on-chip analytics combined with sensor pre-processing. It enables efficient system performance. This allows OEMs and Tier-1 suppliers to support front camera applications. It uses high-resolution 8-MP cameras for precise signal processing. It adds enhanced features to the ADAS systems such as drive assisted technologies.

TDA4VM processors are capable of simultaneously operating four to six 3MP cameras. It also integrates other sensing modalities such as radar, LIDAR and ultrasonic on one chip. This allows TDA4VM to act as the centralized processor for ADAS. It also enables critical features for automated parking such as surround view and image processing for displays. This enhances vehicle perception for 360 degrees of awareness.

The DRA829V processor integrates the computing functions required for modern vehicles. It incorporates a PCIe switch on-chip. It also features an eight-port gigabit TSN-enabled Ethernet switch. This can ensure high-performance computing functions and communications throughout the car.

The processor is combined with the ability to support both ASIL-D safety-critical and non-safety-critical operations. These computing and communication features enable OEMs and Tier-1 suppliers to support mixed-criticality applications on one device. Higher bandwidth on-chip also allows developers to manage software development and validation in vehicles. It translates to more dynamic updates and upgrades.

With the increasing trends in ADAS applications, this new processing platform can upgrade the current automotive sub-systems for more precise and efficient automotive systems.
