RISC-V Comes to PC: SiFive Introduces HiFive Unmatched Development Board
RISC-V architecture is a relatively new Instruction Set Architecture (ISA) developed at the University of California Berkeley. Starting as a "short, three-month project" the RISC-V ISA is a fifth generation of the Reduced Instruction Set Computing (RISC) ideology. A company working on this technology and helping to grow the ecosystem is SiFive. Today, they announced a big step forward for the ecosystem that will enable developers to make and optimize even more software for this architecture and platform. Called the HiFive Unmatched, the development board represents the first entry of RISC-V ISA to the world of personal computing, with its Mini-ITX form factor and PC-like connectors of power supply and I/O.
The board is home to SiFive's FU740 SoC, a five-core heterogeneous, coherent processor with four SiFive U74 cores, and one SiFive S7 core. This SoC is capable of smooth Linux OS operation, giving the developers a good platform to do their optimizations for. There is 8 GB of onboard DDR4 RAM (unknown frequencies and timing), a MicroSD card slot, and one PCIe 3.0 x4 M.2 slot for system storage. To connect the board to the outside world, you get one Gigabit Ethernet port. For user I/O there are four USB 3.2 Gen 1 Type-A ports (1 Charging port) and one MicroUSB Console port. To power the board, you need a proper power supply with a 24-pin power connector. If you plan to build a PC based on the Unmatched board, you would need a standard ITX case, as it comes in the standard Mini-ITX (170x170 mm) form factor.
