Instruction (RISC-V)
An instruction is a machine-level operation encoded as a binary word.
In the base RISC-V ISA, standard instructions are 32 bits wide. The compressed extension adds 16-bit compressed instructions.
Formats
RISC-V uses six standard 32-bit instruction formats:
Each format arranges the opcode, register fields, and immediate bits differently.

A compressed instruction is a 16-bit RISC-V instruction encoding.
It is part of the compressed extension and represents a common operation in a shorter form than the standard 32-bit instruction. Compressed mnemonics are commonly prefixed with
