Microsemi unveiled PolarFire FPGA + RISC-V SoC about one year ago, but at the time, development was done on a $3,000 platform with SiFive U54 powered HiFive Unleashed board combined with an FPGA add-on board from Microsemi. I’ve now been informed that Microchip has announced its Linux-capable PolarFire FPGA+RISC-V SoC would start shipping in Q3 2020 at the RISC-V summit and that a development kit will be sold for a few hundred dollars. PolarFire SoC FPGA PolarFire SoC FPGA key features and specifications: Mid-Range FPGA optimized for Low Power High-speed serial connectivity with built-in multi-gigabit/multi-protocol transceivers from 250 Mbps to 12.7 Gbps Up to 461k logic elements consisting of a 4-input Look-Up Table (LUT) with a fracture-able D-type flip-flop Up to 31.6 Mb of RAM Power optimized transceivers Up to 1420 18 × 18 multiply-accumulate blocks with hardened pre-adders Integrated dual PCIe for up to ×4 Gen 2 Endpoint […]
Google ADT-3 is a Developer-Focused TV Box for Android TV on Android 10
Back in 2014, Google killed Google TV and announced Android TV, and as a result, introduced ADT-1, the first developer kit specifically designed for Android TV. Since then ADT-2 was introduced in 2018 in an HDMI stick form factor, and now the company has announced the launch of Android TV on Android 10 together with ADT-3 devkit targetting Android TV app development for Android 10. The “developer kit” just looks like a standard TV box, although It’s really tiny and comes with what looks like a voice remote control. Google did not provide the full specifications, but ADT-3 is equipped with a quad-core Cortex A53 processor coupled with 2GB DDR3 memory, and supports 4Kp60 HDR video playback and output via an HDMI 2.1 output port. That probably means the box is powered by an Amlogic S905X2 processor since few other TV box SoCs combine 4x A53 cores with HDMI 2.1. […]

FreeMesh WiFi 5 Mesh Network Router Runs OpenWrt
FreeMesh W1326 LTE Router Mesh Network Access FreeMesh has launched an open-source mesh router, the WE1326 LTE FreeMesh Router (included are two nodes) that runs OpenWrt open-source operating system. Open Source and “Hackable” Mesh System FreeMesh enters the mesh market with source code posted on Gitlab, a user-hackable/customizable mesh in other words. FreeMesh uses OpenWrt – the OpenWrt project is a Linux operating system aimed at embedded systems. The focus is on removing the need for a static firmware, where there is only one option for software for the hardware being purchased. The Offerings and Markets The company is targeting the residential market, where most mesh systems are almost double the $150.00 price tag of the FreeMesh. It is reported that there are other ZBT WE826-WD based mesh routers on the market, check out the LinuxGizmos.com article for more information. FreeMesh Specifications FreeMesh Router CPU Dual Core 880MHz MediaTek MT7621AT ROM SPI […]
Testing NVIDIA Jetson Nano Developer Kit with and without Fan
A few weeks ago I received NVIDIA Jetson Nano for review together with 52Pi ICE Tower cooling fan which Seeed Studio included in the package, and yesterday I wrote a getting started guide showing how to setup the board, and play with inference samples leveraging the board’s AI capabilities. I’ll now test the board with the stock heatsink in both 5W and 10W modes, and see if thermal throttling does occur, and then I’ll fit the tower cooling fan to find out if we can extract more performance that way and how much lower the CPU temperature is.
