Abstract

Abstract : Large format IoT displays support a range of exciting visual experiences which are encountered in our day‐to‐day lives. Four processor roles, media player, display controller, touch controller and CV/AI module, leverage four processor types, scalar, vector, spatial and matrix, to power these experiences. Algorithm characteristics such as arithmetic, memory access and data‐dependence complexity influence the suitability of an architecture to a workload. Including, GPUs to rendering, CPUs to interactive application, and FPGAs to custom video pipelines. Programmatic advertising, touch‐less kiosks and CODEC enhancements to minimize bitrate of 8K video streams can require inference (AI) workloads. Matrix (VPU) type processors are designed to address this workload type. The narrow pitch LED wall display market is growing at 10x the overall video wall display market rate and leverages spatial FPGA processing in LED controllers, also requiring 8K resolution at smaller surface area sizes as pixel pitch reduces. Requirements on each heterogenous processor type is concluded to be growing with the combination of market trends.
