AI Technical Summary

⚠Technical Problem

Existing technologies struggle to efficiently process signal fusion from multiple data sources, especially in autonomous driving and self-driving applications, where sensor-generated signals are processed inefficiently and fail to effectively utilize the potential of commercially available processing units.

⚗Method used

Employing a direct memory access (DMA) controller, it performs aggregation and scattering operations by receiving redirected write and read requests, and combines buffers and compute node pools to achieve efficient processing of signal streams.

🎯Benefits of technology

It improves the efficiency of signal processing and the utilization of computing resources, reduces computing latency, and enhances data processing capabilities in autonomous driving and self-driving applications.

Abstract

Example methods, apparatuses, and / or articles of art are disclosed that can be implemented, wholly or partially, in conjunction with processing signal streams. In one application, a direct memory access (DMA) controller may perform a clustering operation, at least in part, based on one or more redirected write requests, to obtain one or more data items from memory; to translate the obtained data items to one or more addresses in the memory; and to perform a scattering operation based on the one or more addresses.
