In his speech, Mr. Cai Zheng introduced TI's comprehensive technology layout and innovative solutions in the field of ADAS , especially the company's new AWR2944 automotive millimeter-wave radar sensor launched at the 2022 International Consumer Electronics Show (CES 2022) . The sensor is about 30 % smaller than the current millimeter-wave radar sensor ; it enhances target detection and improves resolution by 33% to avoid collisions; it can sense oncoming vehicles at a range 40% farther than before , further improving the vehicle's performance in rapid object detection, blind spot monitoring, and efficient turning and corner navigation, helping automakers improve the object sensing capabilities of ADAS.

The design of driver assistance systems is full of challenges and requires consideration of functional safety requirements, cost , and many other considerations. In recent years, emerging trends in the ADAS field have emerged one after another: Level 3+ vehicle architectures have been continuously upgraded, and radars have also played an important role in emerging application scenarios such as assisted parking/automatic parking, door sensing, and in-vehicle sensing.

With a wide range of automotive products and deep expertise, TI helps Chinese customers easily design flexible ADAS systems in many ways:

• Perception: Perception is the foundation of ADAS systems. TI mmWave radar solutions enable safer and easier driving experiences by sensing and reacting to external and internal environments .

• Processing: TI leveraged decades of automotive and functional safety expertise to design the Jacinto™ 7 processor platform to address sensing, parallel operation and system-level challenges. The Jacinto™ 7 processor brings real-world performance to automotive ADAS and systems and helps reduce system costs, making ADAS technology more accessible and accessible.

• Communications: As perception capabilities continue to improve, the demand for data throughput is also increasing. TI provides serializer/deserializer products to optimize high-speed data transmission in ADAS system camera designs while reducing system size and cost.

Enhancing ADAS with innovative technologies

During the conference, TI also showcased its latest ADAS products, Jacinto™ 7 TDA4x and AWR2944 evaluation module. With the popularization of easy-to-implement and cost-effective advanced driver assistance, automotive safety and convenience features will become more mainstream and affordable.

Jacinto™ 7 TDA4x Evaluation Module Powered by Jacinto™ 7 processor Fusion of deep learning and traditional computer vision for a safer ADAS central computing platform. TI TDA4x processors provide efficient deep learning results while achieving high-performance ADAS computing with only 5-20W power consumption. This reference design uses a binocular depth accelerator to generate 192 disparities at 80M/sec, a visual processing accelerator supports up to 180 degrees of binocular correction and up to 720MP/sec processing speed, and a C7x digital signal processor (80 GFLOPS) and matrix multiplication accelerator (8 TOPS) to accelerate deep learning and signal processing. It can simultaneously connect to 8 2M pixel cameras for low-speed unmanned parking and high-speed autonomous driving functions.
