TI’s TDA3x System-on-Chip （SoC） is a highly optimized and scalable family of devices designed to meetthe requirements of leading Advanced Driver Assistance Systems （ADAS）。 The TDA3x family enablesbroad ADAS applications in automobiles by integrating an optimal mix of performance， low power， smallerform factor and ADAS vision analytics processing that aims to facilitate a more autonomous and collisionfree

driving experience.

The TDA3x SoC enables sophisticated embedded vision technology in today’s automobile by enabling theindustry’s broadest range of ADAS applications including front camera， rear camera， surround view， radar，and fusion on a single architecture.

The TDA3x SoC incorporates a heterogeneous， scalable architecture that includes a mix of TI’s fixed andfloating-point TMS320C66x digital signal processor （DSP） generation cores， Vision AccelerationPac（EVE）， and dual-Cortex-M4 processors. The device allows low power profile in different package options（including Package-On-Package） to enable small form factor designs. TDA3x SoC also integrates a hostof peripherals including multi-camera interfaces （both parallel and serial） for LVDS-based surround viewsystems， displays， CAN and GigB Ethernet AVB.

The Vision AccelerationPac for this family of products includes embedded vision engine （EVE） offloadingthe vision analytics functionality from the application processor while also reducing the power footprint.

The Vision AccelerationPac is optimized for vision processing with a 32-bit RISC core for efficient programexecution and a vector coprocessor for specialized vision processing.Additionally， Texas Instruments provides a complete set of development tools for the Arm， DSP， and EVEcoprocessor， including C compilers， a DSP assembly optimizer to simplify programming and scheduling，and a debugging interface for visibility into source code execution.The TDA3x ADAS processor is qualified according to AEC-Q100 standard.
