In doing so they have been able to unleash around 50 GFLOPS of extra compute and demonstrate 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 (3200x2000) image. This will enable automotive customers to use IMG BXS GPUs with OpenCL to achieve maximum performance per watt on TDA4 SoCs for sensor processing workloads – such as camera, radar, and lidar - augmenting other compute accelerators existing in the platform.
Commenting 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.”
MulticoreWare optimised 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.
According to Jake Kochnowicz, VP of Product Management, Imagination, “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.”
