Friday Hack Chat: Open Source Silicon

This Friday, Hackaday.io will be graced with purveyors of Open Source Silicon. Join us in the Hackaday.io Hack Chat this Friday, April 14 at noon PDT (19:00 UTC) for a conversation with SiFive, an ‘Open’ silicon manufacturer.

This week, we’re sitting down with SiFive, a fabless semiconductor company and makers of the HiFive1, an Open Hardware microcontroller that you can just go out and buy. Late last year, SiFive released the HiFive1, an Arduinofied version of SiFive’s FE310 System on Chip. This SoC is a RISC-V core and one of the first microprocessors that is completely Open Source. It is …read more

Hands On With The First Open Source Microcontroller

2016 was a great year for Open Hardware. The Open Source Hardware Association released their certification program, and late in the year, a few silicon wizards met in Mountain View to show off the latest happenings in the RISC-V instruction set architecture.

The RISC-V ISA is completely unlike any other computer architecture. Nearly every other chip you’ll find out there, from the 8051s in embedded controllers, 6502s found in millions of toys, to AVR, PIC, and whatever Intel is working on are closed-source designs. You cannot study these chips, you cannot manufacture these chips, and if you want to use …read more

HiFive1: RISC-V In An Arduino Form Factor

The RISC-V ISA has seen an uptick in popularity as of late — almost as if there’s a conference going on right now — thanks to the fact that this instruction set is big-O Open. This openness allows anyone to build their own software and hardware. Of course, getting your hands on a RISC-V chip has until now, been a bit difficult. You could always go over to opencores, grab some VHDL, and run a RISC-V chip on an FPGA. Last week, OnChip released the RISC-V Open-V in real, tangible silicon.

Choice is always a good thing, and now SiFive, …read more
