OSZU3 System-in-Package (SiP) combines AMD Xilinx Zynq UltraScale+ MPSoC with 2GB RAM, PMIC, passive components

Octavo Systems has collaborated with AMD Xilinx for the OSZU3 system-in-package (SiP) that combines Zynq UltraScale+ MPSoC ZU3 with up to 2GB RAM, power management circuitry, and other components into a compact (40×20.5mm) 600-ball BGA package. We’ve already written about other Octavo Systems SiPs in the past with solutions like OSD3358x (TI Sitara AM3358) and OSD32MP15x (STMicro STM32MP1), but the OSZU3 packs a much more powerful and flexible chip with the AMD Xilinx Zynq UltraScale+ MPSoC offering both Cortex-A53 & Cortex-R5F cores, Arm Mali-400 GPU, and FPGA fabric. Octavo Systems OSZU3 SiP specifications: SoC – AMD Xilinx Zynq UltraScale+ MPSoC ZU3 with CPU – 4x Arm Cortex-A53 up to 1.2GHz, 2x Arm Cortex-R5F up to 500MHz GPU – Arm Mali-400 FPGA 154K System Logic Cells 141K Flip-Flops 71K CLB LUTs 360 DSP Slices 7.6 Mb Block RAM System Memory – 2GB LPDDR4 Storage – 128MB SQPI, and 4K EEPROM (by […]

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 […]

FOSDEM 2022 schedule with embedded Linux, IoT, automotive… sessions

While typically taking place in Brussels, Belgium, FOSDEM 2022 will take place online just like FOSDEM 2021 due to COVID-19 restrictions. The good news is that it means anybody can attend it live from anywhere in the world, and makes it more like “FOSDIM”, replacing European with International, in “Free and Open Source Developers’ European Meeting”. FOSDEM 2022 will take place on February 5-6 with 637 speakers, 718 events, and 103 tracks. I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Computer Aided Modeling and Design”, “FOSS on Mobile Devices”, “Libre-Open VLSI and FPGA”, and others. Saturday, February 5, 2022 12:30 – 13:00 – Five mysteries in Embedded Linux by Josef Holzmayr Once you start out in embedded Linux, there is a lot to do. Some things are obvious, some less so.
