TI ADAS chips boost performance, reduce power consumption
October 16, 2013 by John Day
Texas Instruments Incorporated (TI) unveiled an automotive System-on-Chip (SoC) family, TDA2x, for advanced driver assistance systems (ADAS).
The TDA2x device family is said to combine high performance, vision analytics, video, graphics and general purpose processing cores in a low power envelope, enabling a broad range of ADAS applications including front camera, surround view and sensor fusion.
The new SoCs are based on a heterogeneous, scalable architecture that includes TI’s fixed-and floating-point C66x DSP cores, a fully programmable Vision AccelerationPac, ARM® Cortex™-A15 MPCore™ processors, and dual Cortex-M4 cores, along with video and graphics cores and a host of peripherals.
Delivering more than 8x compute performance at the same power budget for advanced vision analytics in a more cost-effective footprint, TI’s programmable Vision AccelerationPac is designed to run low to mid-level vision processing functions, offloading the DSP and ARM cores and enabling more ADAS algorithms to run simultaneously. The result is optimal performance at the lowest power footprint.
TI ADAS business manager Brooke Williams said the Vision AccelerationPac contains one or more multiple Embedded Vision Engines (EVEs), to offer a purpose built ADAS accelerator like no other on the market today. An optimized vector coprocessor and a 32-bit programmable RISC core support flexible development.
Williams said that with the TDA2x family, TI’s customers will be able to fully achieve embedded automotive vision by enabling the industry’s broadest range of ADAS applications on a common architecture, allowing algorithm investments to be shared across multiple systems.
Front camera, surround view and sensor fusion
The TDA2x enables front camera applications including high beam assist, lane keep assist, advanced cruise control, traffic signal recognition, pedestrian/object detection, and collision avoidance to run simultaneously.
Additionally, the TDA2x enables park assist applications including intelligent 2D and 3D surround view and rear collision warning, and can run a pedestrian/object detection algorithm developed for the front camera. TI’s TDA2x also serves as a central processor for fused radar and camera sensor data, allowing more robust ADAS decision making.
TI offers royalty-free software libraries and a framework of vision and imaging functions to take full advantage of the TDA2x and Vision AccelerationPac’s architecture while reducing development efforts and time to market. A suite of development boards is also available, along with TI’s field team support.
ISO 26262 functional safety deliverables
The TDA2x is under development respecting the relevant requirements of ISO 26262 functional safety standard. Supporting safety documentation will be available to customers upon device PPAP and release.
Power Management ICs
TI’s TPS659039-Q1 power management IC has been specifically designed for seamless operation together with the TDA2x SoC family. The TPS659039-Q1 includes features that manage all system power requirements for TI’s TDA2x processors while maximizing power efficiency and reliability. TI’s PMIC solutions are designed specifically to pair with TI’s TDA2x, which helps customers accelerate their time to market and reduce their development risk.
