bge
bge
branch if greater than or equal signed
Operation: if ((signed) rA >= (signed) rB)
then PC
←
PC + 4 + σ (IMM16)
else PC
←
PC + 4
Assembler Syntax:
bge rA, rB, label
Example:
bge r6, r7, top_of_loop
Description:
If (signed) rA >= (signed) rB, then
bge transfers program control to the instruction at
label. In the instruction encoding, the offset given by IMM16 is treated as a signed
number of bytes relative to the instruction immediately following
bge. The two least-
significant bits of IMM16 are always zero, because instruction addresses must be
word-aligned.
Instruction Type: I
Instruction Fields: A = Register index of operand rA
B = Register index of operand rB
IMM16 = 16-bit signed immediate value
