32-Bit Instruction Set
ADDI
Add Immediate
Operation:
RA
← RA + (0x00.00 : K : IMM5)
Assembler Syntax:
ADDI %rA,IMM5
Example:
Not preceded by PFX:
ADDI %L5,6 ; add 6 to %L5
Preceded by PFX:
PFX %hi(1000)
ADDI %g3,%lo(1000) ; ADD 1000 to %g3
Description:
Not preceded by PFX:
Adds 5-bit immediate value to register A, stores result in register A. IMM5 is in the
range [0..31].
range [0..31].
Preceded by PFX:
The immediate operand is extended from 5 to 16 bits by concatenating the
The immediate operand is extended from 5 to 16 bits by concatenating the
contents of the K-register (11 bits) with IMM5 (5 bits). The 16-bit immediate value
(K : IMM5) is zero-extended to 32 bits and added to register A.
(K : IMM5) is zero-extended to 32 bits and added to register A.
