WebApr 20, 2024 · ADDW and SUBW are RV64I-only instructions that are defined analogously to ADD and SUB but operate on 32-bit values and produce signed 32-bit results. Overflows are ignored, and the low 32-bits of the result is sign-extended to 64-bits and written to the destination register. thus a sign bit.

While GPRs are accessible at any privilege level, CSRs are defined at a specific privilege level and can only be accessed by that level and any levels of higher privilege. The Privileged Spec defines both a common set of CSRs …
ADDIW is an RV64I instruction that adds the sign-extended 12-bit immediate to register rs1 and produces the proper sign-extension of a 32-bit result in rd. Overflows are ignored and the result is the low 32 bits of the result sign-extended to 64 bits.
