It includes an instruction set architecture (ISA) using an open-source license. It is the original flagship project of the OpenCores community. The first (and as of 2019 [update] only) architectural description is for the OpenRISC 1000 ("OR1k"), describing a family of 32-bit and 64-bit processors with optional floating-point arithmetic and ...

RISC-V [b] (pronounced "risk-five" [2]: 1 ) is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. . The project began in 2010 at the University of California, Berkeley, transferred to the RISC-V Foundation in 2015, and on to RISC-V International, a Swiss non-profit entity, in November 20
The relevant term is of the porting target is computer architecture; it comprises the instruction set(s) and the microarchitecture(s) of the processor(s), at least of the CPU. The target also comprises the "system design" of the entire system, be it a supercomputer , a desktop computer or some SoC , e.g. in case some unique bus is being used.
In the absence of a widely accepted open source hardware license, the components produced by the OpenCores initiative use several different software licenses.The most common is the GNU LGPL, which states that any modifications to a component must be shared with the community, while one can still use it together with proprietary components.
The processor is designed to have 15 cores available, but a spare core will be included during manufacture to cost-effectively allow for yield issues. Power10-based processors will be manufactured by Samsung using a 7 nm process with 18 layers of metal and 18 billion transistors on a 602 mm 2 silicon die .
