  1. Load-store architecture
    • According to 3 sources
    RISC-V is a load-store architecture, meaning three things: (i) Its arithmetic instructions operate only on registers, (ii) Only load and store instructions transfer data to and from memory, and (iii) Data must first be loaded into a register before it can be operated on.
