CLEAR is an open-source FPGA ASIC provided by Efabless’ chipIgnite

Open-source SoC designs are available to run on FPGA hardware, but few make it to silicon due to the costs involved. That’s why a couple of years ago the Google SkyWater PDK (process design kit) was released together with an offer to manufacture up to 100 pieces for free to selected designs in collaboration with Efabless. Efabless chipIgnite is an evolution of that offer with $9,750 being enough funds to manufacture 100 QFN or 300 WCSP parts, or alternatively 1,000 parts for $20 each ($20,000). Based on the company’s Caravel template SoC and the openFPGA generator framework, CLEAR open-source FPGA ASIC design is meant to promote and demonstrate the chipIgnite “paid IC creation” solution. You can participate by joining a group buying campaign on GroupGets to get a development board based on CLEAR for $74.99 plus shipping. CLEAR open-source FPGA ASIC features: FPGA – Small 8×8 (64) CLB eFPGA CPU […]

India goes RISC-V with VEGA processors

One of the main advantages of RISC-V architecture is that it is open, so any organization with the right skills can develop its own cores, and India’s government has taken up this opportunity with the Microprocessor Development Programme (MDP) helping develop VEGA RISC-V cores locally. Thanks to funding by the Ministry of Electronics and Information Technology (MeitY), the Centre for Development of Advanced Computing (C-DAC) managed to design five RISC-V processors ranging from a single-core 32-bit RISC-V microcontroller-class processor to a Linux capable quad-core 64-bit out-of-order processor. Key features of the five VEGA cores developed by the C-DAC: VEGA ET1031 – 32-bit single-core 3-stage in-order RV32IM processor with AHB/AXI4.bus, optional MMU, optional Debug VEGA AS1061 – 64-bit single-core 6-stage in-order RV64IMAFDC processor with 8KB D-cache, 8KB I-cache, FPU, AHB/AXI4 bus VEGA AS1161 – 64-bit single-core 16-stage pipeline out-of-order RV64IMAFDC processor with 32KB D-cache, 32KB I-cache, FPU, AHB/AXI4/ACE bus VEGA AS2161 […]

Golioth IoT development platform offers Zephyr SDK, support for nRF9160, ESP32, and over 100 other platforms

There are already plenty of IoT development platforms, but here’s another one with Golioth that relies on a Zephyr SDK, “first-tier” support for Nordic Semiconductor nRF9160 (cellular) and Espressif Systems ESP32-C3 (WiFi), as well as a QEMU-based simulator for easy testing. The use of an open-source Zephyr SDK even enables them to support over 100+ hardware components, and the company, also called Golioth, says their platform scales from one device for evaluation to one million devices during deployment, thanks notably to a free Dev Tier account to get started at no cost. Some of the other highlights of Golioth include: “Secure by Default” communication over efficient protocols like CoAP and soon MQTT Access to Device Services like Software updates that include secure boot and firmware management Real-time NoSQL database (LightDB) that can be useful for creating Digital Twins and synchronization Time-series database (LightDB Stream) for storing and querying sensor data […]

KrakenSDR is a 5-channel software-defined radio based on RTL-SDR

KrakenRF KrakenSDR is a software-defined radio (SDR) with five coherently-operated receive channels that’s basically the equivalent of five cheap RTL-SDR USB dongles based on the R820T2 chip with a single board housed in a metal enclosure equipped with five custom antennas. KrakenSDR operates in the usual 24 MHz to 1766 MHz tuning range and connects over USB to the host system, preferably a Raspberry Pi4 as the open-source Core DAQ and DSP software is designed for the popular single board computer. There’s also an Android for location finding that is free to use for non-commercial applications. KrakenSDR specifications: Five-channel, coherent-capable RTL-SDR (5x R820T2 tuners + RTL2832U ADCs), all clocked to a single local oscillator, ESD protection 5x SMA Antenna inputs Tuning Range – 24 MHz to 1766 MHz standard R820T2 RTL-SDR range and possibly higher with hacked drivers Built-in automatic coherence synchronization hardware Automatic coherence synchronization and management via provided […]
