SiFive Introduces Freedom U500 and E500 Open Source RISC-V SoCs

Open source used to be a software thing, with the hardware design being kept secret for fear of being copied, but companies such as Texas Instruments realized that from a silicon vendor perspective it would make perfect sense to release open source hardware designs with full schematics, Gerber files and SoM, to allow smaller companies and hobbyists, as well as the education market, normally not having the options to go through standard sales channels and the FAE (Field Application Engineer) support, to experiment with the platform and potentially come up with commercial products. That’s exactly what they did with the Beagleboard community, but there’s still an element that’s closed source, albeit documented: the processor itself. But this could change soon, as SiFive, a startup founded by the creators of the free and open RISC-V architecture, has announced two open source SoCs with Freedom U500 processor and Freedom E300 micro-controller. Freedom […]

Digilent ARTY is a $99 Xilinx Artix-7 FPGA Board with Arduino Headers

Low cost FPGA boards with Arduino headers are nothing new, as we’ve seen before with Arduissimo and Papilio DUO, but both of these boards are based on Spartan 6 FPGA, while the recent Digilent ARTY board is powered by an Artix-7 FPGA. Beside the hardware differences, Spartan 6 FPGAs only support Xilinx ISE Design Suite, while Artix-7 parts are also supported by Vivado Design Suite, which according to Xilinx has a much better workflow and user interface. Digilent ARTY specifications: FPGA – Xilinx XC7A35T-L1CSG324I with 33,280 logic cells, 1,800 Kb block RAM, 90 DSP slices, and 250 I/O pins System memory – 256 MB DDR3L SDRAM Storage – 16 MB of QSPI Flash Connectivity – 10/100M Ethernet Expansion interfaces 4 Digilent compatible Pmod interfaces enabling 32 user I/O pins: 2 Pmods routed as differential pairs, paired to fit dual-wide Pmods Arduino UNO R3 shield / chipKit interface Debugging – USB-UART Interface, […]
