MulticoreWare and Imagination collaboration accelerates automotive compute workloads 

Unlocking the compute potential of the IMG BXS GPU on the TDA4VM processor delivers x100 performance gains.

MulticoreWare Inc and Imagination Technologies announce that they have enabled GPU compute on the Texas Instruments TDA4VM processor, unleashing around 50 GFLOPS of extra compute and demonstrating a massive improvement in the performance of common workloads used for autonomous driving and advanced driver assistance systems (ADAS). 

The collaboration has achieved over 100x performance gains when running a stereo block matching (StereoBM) algorithm on the GPU rather than on the CPU on a high resolution (3200×2000) image. This enables automotive customers to use IMG BXS GPUs with OpenCL™ to achieve maximum performance per watt on TDA4 SoCs for sensor processing workloads (camera, radar, and lidar) augmenting other compute accelerators existing in the platform. 

Vish Rajalingam, VP & GM, Mobility & Transportation BU, MulticoreWare said, “The automotive software revolution is driving the need for seamless intelligent features on low-power SoCs. Our experience with OpenCL and Edge AI across all major AI accelerators, GPUs, and SoCs unlocks incredible possibilities for the future of mobility. We’re thrilled to partner with Imagination and their customers to collaboratively transform this exciting landscape.” 

MulticoreWare optimized the StereoBM algorithm to leverage GPU cores efficiently. The IMG BXS-4-64 GPU intrinsics and adaptive memory handling helped achieve optimal performance on higher resolution camera data.  

Jake Kochnowicz, VP of Product Management, Imagination said, “The graphics processor can do so much more in a car than its traditional job of rendering pixels on the displays. It is also a flexible, programmable, and high-performance option for supporting a vehicle’s ADAS workloads.  In a world where hardware is agreed very early in the lifecycle of a software-defined vehicle, GPUs are becoming a key differentiator that can unlock new functionality with a user-friendly software environment, just as this partnership with MulticoreWare has demonstrated.” 

Imagination’s white paper, “The Use of GPU Compute in Automotive“, explains the benefits of using the GPU for compute tasks in vehicles and how Imagination GPUs are designed to execute such workloads efficiently.
