Open supply computing skilled Take pleasure in Digital is providing free ultra-compact M.2 FPGA-based accelerator boards, able to performing as a Linux-capable RISC-V laptop, to anybody keen to assist with creating the units and their ecosystem.
Take pleasure in Digital has been engaged on constructing a completely open supply improvement board for RISC-V initiatives based mostly across the SQRL Acorn, an organization PCI Categorical M.2 FPGA board initially constructed to speed up Bitcoin mining. The rising issue of mining the cryptocurrency coupled with the launch of extra highly effective application-specific built-in circuit (ASIC) {hardware}, although, means they’re all-but ineffective for his or her supposed objective – making them preferrred for upcycling into one thing new.
The LiteX-Acorn-Baseboard is the primary Linux-capable RISC-V-based open-hardware RISC-V improvement board to be constructed across the Acorn, however Take pleasure in Digital would not need to be alone: It is providing builders one in all 20 Acorn boards freed from cost, for set up into any laptop with a PCIe M.2 slot obtainable — and to be used as both a second RISC-V-based system or for internet hosting an FPGA-based acceleration core.
“Have a free PCIe-M2 slot in your Linux laptop? Why not put a 100 per cent open RISC-V-Linux laptop in it or create your individual FPGA based mostly accelerator – with none JTAG/UART cable,” Take pleasure in Digital writes of its supply. “20 Acorn boards to provide away for builders keen to contribute/lengthen this!”

“Humorous factor: The LiteUART Linux driver from Antmicro is used on each aspect for UART communication: By the VexRiscv SoC operating Linux and by the Host to create the digital UART over PCIe. This final lacking piece has simply been added by Ilia S.”
The important thing enchantment to the Acorn, when operating Take pleasure in Digital’s code, is that it is utterly open supply — from the LiteX system-on-chip with its RISC-V cores to the DDR3 and PCI Categorical interfaces. There’s room left, too, for a developer to implement their very own logic alongside the Linux-capable RISC-V SoC.
Take pleasure in Digital is at present taking purposes for the free board on Twitter, with directions for constructing the software program for the Acorn obtainable on GitHub.
