Assembler Syntax

BGEI as, imm, label

Description

(please consult the Xtensa ® Instruction Set Architecture Reference Manual for any cross references and additional information)

BGEI branches if address register as is two's complement greater than or equal to the constant encoded in the r field. The constant values encoded in the r field are not simply 0..15. For the constant values that can be encoded by r, see Xtensa Instruction Set Architecture Reference Manual.

The target instruction address of the branch is given by the address of the BGEI instruction, plus the sign-extended 8-bit imm8 field of the instruction plus four. If the address register as is less than the constant, execution continues with the next sequential instruction.

The inverse of BGEI is BLTI.

Operation

if AR[s] >= B4CONST(r) then
	nextPC ← PC + (imm8724||imm8) + 4
endif
