bgeu
bgeu
branch if greater than or equal unsigned
Operation: if ((unsigned) rA >= (unsigned) rB)
then PC
PC + 4 + σ (IMM16)
else PC
PC + 4
Assembler Syntax:
bgeu rA, rB, label
Example:
bgeu r6, r7, top_of_loop
Description:
If (unsigned) rA >= (unsigned) rB, then
bgeu 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
bgeu. 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
