Getting Started with NVIDIA Jetson Nano Devkit: Inference using Images, RTSP Video Stream

Jetson Nano RTSP Stream Inference

Last month I received NVIDIA Jetson Nano developer kit together with 52Pi ICE Tower Cooling Fan, and the main goal was to compare the performance of the board with the stock heatsink or 52Pi heatsink + fan combo. But the stock heatsink does a very good job of cooling the board, and typical CPU stress tests do not make the processor throttle at all. So I had to stress the GPU as well, as it takes some efforts to set it up all, so I’ll report my experience configuring the board, and running AI test programs including running objects detection on an RTSP video stream. Setting up NVIDIA Jetson Nano Board Preparing the board is very much like you’d do with other SBC’s such as the Raspberry Pi, and NVIDIA has a nicely put getting started guide, so I won’t go into too many details here. To summarize: Download the latest firmware image (nv-jetson-nano-sd-card-image-r32.2.3.zip at the time of the review) …

Qualcomm Snapdragon 7c & 8c Processors Target Entry-Level & Mainstream Mobile PCs

Nearly exactly one year ago, Qualcomm announced the Snapdragon 8cx processor for always-on always-connected PCs, and lateron Qualcomm and UL released PCMark 10 benchmark results showing Snapdragon 8cx had similar performance to a 15W Intel Core i5-8250U Kaby Lake-R processor, but with much better efficiency. The price of such laptops is still fairly high with Samsung Galaxy Book S announced in August for $1,000, and possibly canceled at this stage. Microsoft SQ1 powered Surface Pro X tablet is the only system based on Qualcomm Arm technology (customized version of Snapdragon 8cx) available now, and also sells for $1,000 and up. Qualcomm has now unveiled Snapdragon 7c and 8c arm processor to address the entry-level and mainstream markets of connected mobile PCs.
