Launched in February 2021 as the first in the ARKTIKA constellation and serving as an Arctic monitoring system, ARKTIKA-M1 transmits at the lower end of the X-Band – out of range of most affordable software-defined radio systems, but receivable with a suitable downconverter capable of shifting ...

Alibaba Cloud Opens Up IoT Technology Development Platform | Wang Cindy, Alibaba Cloud

by RISC-V Community News on Blog Archives - RISC-V International 27 January 2022 16:34 UTC

Alibaba Cloud, the digital technology and intelligence backbone of Alibaba Group, announced it has opened the source code of Yun on Chip (YoC), its proprietary full-stack technology development platform for IoT devices. This initiative follows the company open-sourcing the XuanTie IP core series – the custom-built processors based on RISC-V instruction-set architecture – in October this year.   “This announcement is further proof of our continuous support for the RISC-V software ecosystem ...

Documenting SystemVerilog with Sphinx

by Matthew Ballance on Bits, Bytes, and Gates 24 January 2022 02:57 UTC

I've been digging into a project over the last few months whose value proposition is to simplify the process of connecting simulation-like environments and things like reference models, testbench languages, etc. I'll write more (likely much more) about this project in the future. This post, however, is about documentation and, specifically, documentation for SystemVerilog code.As you can imagine,

Google Research Releases Circuit Training, an Open-Source Framework for Automated Chip Floorplanning

by Gareth Halfacree on FOSSi Archives - AB Open 21 January 2022 08:43 UTC

Google Research has released the source code for a chip floor-plan generate based on deep reinforcement learning – after publishing a paper demonstrating how effective the approach could be in April last year. “Chip floorplanning is the engineering task of designing the physical layout of a computer chip,” the research team explained in the abstract to their paper. “Despite five decades of research, chip floorplanning has defied automation, requiring months of intense effort by physical ...

Incredible Hack Implements a CPU in a Modular Analogue SynthBuilding a CPU out of discrete digital logic is a right-of-passage for many in the world of free and open source silicon and open hardware, but engineer Kate F. has gone a step further — building a functional CPU using an analogue modular synth. “I’m using VCV Rack. It’s software simulation for Eurorack modular synthesisers, either in conjunction with, or in place of hardware modules,” Kate explains of the project. “You know the ...

Edalize 0.3.0

by Olof Kindgren on Tales from Beyond the Register Map 07 January 2022 14:30 UTC

 Looks like it's time for a new Edalize release. During this development cycle, most of the work has been done under the hood with creating a new internal architecture and refactoring many of the backends. Most of those efforts will bear fruit longer term, but we can already today see the initial work on the flow API, that has been planned for at least two years. We also welcome a new backend for Lattice Nexus devices and some miscellaneous feature additions and bug fixes. Read on for the ...
