IMM

Description

The IMM ﬁeld is sign-extended to 32 bits. The contents of register rA are ANDed with the logical complement of the extended IMM ﬁeld; the result is placed into register rD.

Pseudocode

(rD) ← (rA) ∧ (sext(IMM))

1 cycle

Note

By default, Type B Instructions will take the 16-bit IMM ﬁeld value and sign extend it to 32 bits to use as the immediate operand. This behavior can be overridden by preceding the Type B instruction with an imm instruction. See the imm instruction for details on using 32-bit immediate values.
