Fomu FPGA board fits inside a USB port, Supports Python, RISC-V Softcore

Fomu FPGA Board

Sutajio Ko-usagi launched Tomu, a tiny open source hardware USB board that fits inside a USB port at the very beginning of this year. The company is back with a similarly shaped board, but instead of featuring a Silicon Labs EFM32 Arm Cortex-M0+ microcontroller, Fomu is equipped with a Lattice ICE40 UltraPlus FPGA. Fomu specifications: FPGA – Lattice ICE40UP5K FPGA with 5280 logic cells System Memory – 128 kB RAM for a soft CPU Storage – 1 or 2 MB SPI flash Clock – 48 MHz crystal oscillator USB – 1x USB 2.0 FS (12 Mbps) port Misc – 4x buttons, 1x RGB LED The default Fomu firmware exposes a USB bootloader running a RISC-V softcore, and the platform is powerful enough to run a port of Python. It’s also possible to experiment with LM32 and OpenRISC softcores on the platform. Using the board is pretty straightforward as just you […]

BOOM Open Source RISC-V Core Runs on Amazon EC2 F1 Instances

BOOM RISC-V Core Block Diagram

The Berkeley Out-of-Order Machine (BOOM) is an open source RV64G RISC-V core written in the Chisel hardware construction language, and mainly ASIC optimized. However, it is also usable on FPGAs, and developers support the FireSim flow to run BOOM at over 90 MHz on Xilinx Ultrascale+ FPGAs found in Amazon EC2 F1 instances. The BOOM core was created at the University of California, Berkeley in the Berkeley Architecture Research group, in order to create a high performance, synthesizable, and parameterizable core for architecture research. Key features of BOOM core: ISA – RISC-V (RV64G) Synthesizable FPGA support Parameterized Floating Point (IEEE 754-2008) Atomic Memory Op Support Caches & Virtual Memory Boots Linux Privileged Arch v1.11 External Debug BOOM is said to be inspired by the MIPS R10k and the Alpha 21264 out–of–order processors, based on a unified physical register file design (aka as “explicit register renaming”). The source code for the […]

Open Source Hardware SpiderSoM System-on-Module Features Intel MAX 10 FPGA

aries embedded spidersom

When embedded systems companies offer a system-on-module (SoM) and a baseboard, the later is usually open source hardware with all design files provided so that customers can leverage the work for their own baseboard, but files for the SoM are normally not released to customers. Intel MAX 10 FPGA based Aries SpiderSoM and SpiderBase change that, as the company has decided to release both the module and carrier board KiCAD designs under a CERN OHL v1.2 license. SpiderSoM system-on-module specifications: FPGA – Intel MAX 10 FPGA in F256 package from 10M04DC to 10M50DA System Memory – Optional 128/256/512MB DDR3 DRAM for 10M 16/25/40/50 FPGAs Storage – Optional 4 MB SPI NOR, optional 4 GB eMMC flash 230-pin MxM2 edge connector with 178x FPGA GPIO pins, including 13 LVDS transmitters and 54 receivers Misc – RTC with battery backup,  programmable clock generator and PLL, with optional external reference input Power Supply […]

LicheeTang Anlogic EG4S20 FPGA Board Targets RISC-V Development

LicheeTang

LicheePi has already made some interested little development board in the past with products such as LicheePi Zero, and the recently-announced SD card sized LicheePi Nano board, but their  latest development board may ever be more intriguing. LicheeTang features Anlogic EG4S20 FPGA – unrelated to Amlogic – which run a RISC-V softcore,  and all is packaged in a small small form factor as we’ve come to expect with LicheePi boards. LicheeTang specifications: FPGA – Anlogic EG4S20BG256 with 20K logic unit (LUT4/LUT5 hybrid architecture), about 130KB SRAM, 64MBit SDRAM Storage – 8Mbit flash, micro SD card slot, optional SPI NOR flash Expansion Connectors FPC40P socket for RGB LCD, VGA adapter board, or high speed (12-bit 1MSPS) DAC module FPC24P socket for DVP camera, or high speed ADC module Through holes and castellated holes exposing over 130 I/Os Debugging – FPGA JTAG chip connected over micro USB port Misc – RGB LED […]

UltraZed-EV Starter Kit Support Simultaneous 4K Encoding and Decoding with Xilinx Zynq UltraScale+ EV MPSoC

UltraZed EV Starter Kit

Xilinx unveiled Zynq UltraScale+ MPSoC‘s combining Arm Cortex A53/R5 cores with FPGA fabric back in 2015. and we started to see development boards and products based on the solution starting in 2017 with offerings such as AXIOM Board, TRENZ TE0808 SoM, or more recently 96Boards compliant Ultra96 development board. All last three boards have one thing in common: they all use an Zynq UltraScale+ GC MPSoC that adds a Mali-400MP2 GPU to CG MPSoC family. But there’s also a third EV family which standards for “Embedded Vision”, and adds support for 4K H.264 / H.265 hardware video codec capable of simultaneous encode and decode. The platform targets multimedia, automotive ADAS, surveillance, and other embedded vision applications. So far, I don’t think I had seen any boards based on Ultrascale+ EV MPSoC, but AVNet  – following up on their UltraZed-EG starter kit – has now launched an UltraZed-EV starter kit powered […]
