Abstract

Deep learning (DL)-based algorithms are used in many integral modules of ADAS and Automated Driving Systems. Camera based perception, Driver Monitoring, Driving Policy, Radar and Lidar perception are few of the examples built using DL algorithms in such systems. These real-time DL applications requires huge compute requires up to 250 TOPs to realize them on an edge device. To meet the needs of such SoCs efficiently in-terms of Cost and Power silicon vendor provide a complex SoC with multiple DL engines. These SoCs also comes with all the system resources like L2/L3 on-chip memory, high speed DDR interface, PMIC etc to feed the data and power to utilize these DL engines compute efficiently. These system resource would scale linearly with number of DL engines in the system. This paper proposes solutions to optimizes these system resource to provide cost and Power efficient solution. (1) Co-operative and Adaptive asynchronous DL engines scheduling to optimize the peak resources usage in multiple vectors like memory size, throughput, Power/ Current. (2) Orchestration of Co-operative and Adaptive Multi-core DL Engines to achieve synchronous execution to achieve maximum utilization of all the resources. The proposed solution achieves upto 30% power saving or reducing overhead by 75% in 4 core configuration consisting of 32 TOPS.
