SiFive S2 RISC-V Core may be the World’s Smallest 64-bit Embedded Core

Last year, SiFive introduced their first RISC-V cores competing with Arm Cortex-R family of processors thanks to their S7 Series 64-bit RISC-V Core IP providing an answer to Arm Cortex-R7/R8 32-bit real-time processors. The company has now announced the SiFive S2 RISC-V core that it claims to be the world’s smallest 64-bit embedded core, and also the first SiFive IP core without any direct competitive equivalent in the market. For now, there’s only one core in the family with SiFive S21 offering the following key features: RISC-V ISA – RV64IMAC 64-bit AXI Ports Machine and User Mode with 4 Region Physical Memory Protection 3-stage pipeline with Simultaneous Instruction and Data Access 2 Banks of Tightly Integrated Memory (TIM) CLIC (Core Local Interrupt Controller) with 127 interrupts Advanced debug with 4 hardware breakpoints/watchpoints Performance – 1.6 DMIPS/MHz; 3.2 Coremarks/MHz The company compares its to the SiFive S5 cores, which I had not heard about previously, and are competing with Arm Cortex-R4/R5 …

Getting Started with balenaFin Developer Kit, balenaOS and balenaCloud

balena Fin is a carrier board for Raspberry Pi Compute Module 3/3+ designed specifically for industrial applications leveraging fleet management services provided by Balena. I received balenaFin developer kit last month, and in the first part of the reviewed shows how to assemble the kit. I’m now had time to spend more time with the kit, as well as BalenaOS Linux based operating system optimized for running Docker containers on embedded devices, and balenaCloud services to manage a fleet of devices from a web dashboard. I’ve mostly followed the instructions in the getting started guides here and there, and will document what I had to do to prepare the image, flash it to the board, and load a sample docker application locally, and through balenaCloud. Downloading and Configuring BalenaOS for balena Fin You’ll find BalenaOS in the download page. While we are using hardware based on a Raspberry Pi Compute Module, make sure to select “Fin” instead of “Raspberry Pi”. …

Amlogic S905X3, S905Y3 & S905D3 Quad Core Cortex A55 AI Processors Are Coming Soon

Arm Cortex A55 was announced together with Arm Cortex A75 processor as the first core compatible with DynamIQ processing, and so far we’ve seen a few Arm Cortex-A55 cores but mostly combined with Cortex-A75. However after launching their Amlogic S905X2, S905Y2, and S905D2 processors last year, all based on the older and time-tested Arm Cortex-A53 cores, I’ve just found out the company is working on upgrades with S905X3, S905Y3, and S905D3 featuring four Arm Cortex-A55 cores, coupled with an AI processor normally used for voice recognition in TV boxes. We have very little details at this stage, except the new processors will have many of the same features as the S905X2/Y2/D2 models including an Arm Mali-G31 MP2 GPU, HDMI 2.1 up to 4Kp75 resolution and HDR support, 4K H.265, VP9, and AVS2 video decoding, Full HD H.265/H.264 encoding, as well as PCIe and USB 3.0 support. The “AI processor” is extra and likely the same 2.5/5.0 TOPS neural network accelerator …

FCC: That Cheap Chinese TV Box may end up Costing you $147,000

Buying inexpensive TV boxes from China is fun, but in order to provide the lowest possible price, some manufacturers may cut corners, and forgo things like FCC certification. It seems the FCC has noticed an issue an enforcement advisory / public notice entitled “VIDEO TV SET-TOP BOXES, INCLUDING THOSE THAT STREAM INTERNET CONTENT, MUST COMPLY WITH FCC EQUIPMENT AUTHORIZATION REQUIREMENTS” with the threat of fines exceeding $147,000. If you are an individual you may think that you are safe since you are not “marketing” anything, but a footnote explains the meaning of marketing: Importing, advertising and selling are three aspects of “marketing” under the Commission’s rules. The text of the notice further mentions that even just operating the device is a violation, and anyone doing so should stop immediately. The document explains a little more about the fines: Users, manufacturers, importers, and retailers that violate Commission marketing or operating rules may be subject to the penalties authorized by the Communications …
