AI inference using Images, RTSP Video Stream on NVIDIA Jetson Nano Devkit

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 […]

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. Qualcomm Snapdragon 7c Specifications: CPU – Octa-core Kryo 468 processor @ up to 2.45 GHz GPU – Qualcomm Adreno 618 GPU DSP – Qualcomm Hexagon 692 DSP with Hexagon […]

Versalogic Owl Small Form Factor Apollo Lake Embedded Computer Targets Military & Industrial Applications

VersaLogic Owl VL-EPU-4012 Embedded System Computer In October 2019 we reported on the VersaLogic Harrier computer that was slightly bigger than a credit card. Just announced by the company is a new embedded computer system is being developed, the Owl. Basics of the VersaLogic Owl The intended uses are again industry and military-grade applications. The system uses ECC memory and the Embedded Processing Unit (EPU) format. The processing unit is an Intel Atom E39xx Platform, 5th Gen Apollo Lake processor with dual or quad-core options. Strength and Resilience The ECC memory is fixed to the board and can be up to 8 GB in size. This reduces the damage that can be caused by vibration and shock, making the system tough and resilient. Available Ports and Security Hardware-based security is through a TDM 2.0 chip. There are onboard power conditioning, mini-PCIe expansion sockets, analog inputs, standard USB 3.0 and 4x […]
