WebSep 7, 2015 · 1 Answer Sorted by: 5 RISC-V is an ISA (instruction set architecture), not a processor. Thus, the ISA has nothing to say about cache write-back policies or coherency design. Those decisions are left up to the individual processor design teams. In fact, they don't even need to have caches.
