3 Description

The TDA4VM processor family targeted at ADAS and Autonomous Vehicle (AV) applications and built on

extensive market knowledge accumulated over a decade of TI’s leadership in the ADAS processor market.

The unique combination high-performance compute, deep-learning engine, dedicated accelerators for signal

and image processing in a functional safety compliant targeted architecture make the TDA4VM devices a

great fit for several industrial applications, such as: Robotics, Machine Vision, Radar, and so on. The TDA4VM

provides high performance compute for both traditional and deep learning algorithms at industry leading power/

performance ratios with a high level of system integration to enable scalability and lower costs for advanced

automotive platforms supporting multiple sensor modalities in centralized ECUs or stand-alone sensors. Key

cores include next generation DSP with scalar and vector cores, dedicated deep learning and traditional

algorithm accelerators, latest Arm and GPU processors for general compute, an integrated next generation

imaging subsystem (ISP), video codec, Ethernet hub and isolated MCU island. All protected by automotive grade

safety and security hardware accelerators.

Key Performance Cores Overview

The “C7x” next generation DSP combines TI’s industry leading DSP and EVE cores into a single higher

performance core and adds floating point vector calculation capabilities, enabling backward compatibility for

legacy code while simplifying software programming. The new “MMA” deep learning accelerator enables

performance up to 8 TOPS within the lowest power envelope in the industry when operating at the typical

automotive worst case junction temperature of 125°C. The dedicated ADAS/AV hardware accelerators provide

vision pre-processing plus distance and motion processing with no impact on system performance.

General Compute Cores and Integration Overview

Separate dual core cluster configuration of Arm? Cortex?-A72 facilitates multi-OS applications with minimal need

for a software hypervisor. Up to six Arm? Cortex?-R5F subsystems enable low-level, timing critical processing

tasks to leave the Arm? Cortex?-A72’s unencumbered for applications. The integrated “8XE GE8430” GPU

offers up to 100 GFLOPS to enable dynamic 3D rendering for enhanced viewing applications. Building on the

existing world-class ISP, TI’s 7th generation ISP includes flexibility to process a broader sensor suite, support

for higher bit depth, and features targeting analytics applications. Integrated diagnostics and safety features

support operations up to ASIL-D/SIL-3 levels while the integrated security features protect data against modern

day attacks. To enable systems requiring heavy data bandwidth, a PCIe hub and Gigabit Ethernet switch are

included along with CSI-2 ports to support throughput for many sensor inputs. To further the integration, the

TDA4VM family also includes an MCU island eliminating the need for an external system microcontroller.
