difference between mov and movs instruction

27 Dec 2015 The MOV instruction copies the value of Rm into Rd . The MOVS instruction performs the same operation as the MOV instruction, but also updates the N and Z flags. The MVNS instruction takes the value of Rm , performs a bitwise logical negate operation on the value, and places the result into Rd . Color me dense but I just figured out what was going on with these instructions. The ARM processor has a powerful instruction set. But only a subset To return from the subroutine, the mov instruction can be used as shown below. mov pc, lr. The MOV instruction copies the value of Operand2 into Rd . The MVN instruction takes the value of Operand2 , performs a bitwise logical NOT operation on the 6 Sep 2018 7 Nov 2011 Remember that the ARM can perform a certain set of manipulations on the immediate value as part of the barrel shifter that is incorporated into the ARM's Non-Confidential PDF versionARM DUI0379H ARM® Compiler v5.06 for µVision® armasm User GuideVersion 5Home > ARM and Thumb Instructions > MOV Thus the complete add instruction, in assembler format, would be: ADD R0, R1, R2 ;R0 = R1 + R2. Most ARM mnemonics consist of three letters, e.g. SUB, MOV,Instruction Encoding. MOVS. R0, R1. 31 28. 24 21. 20. 15 12. 3 0. (cc). 000 . An ARM word is 32-bits, so a Halfword is 16-bits. • Load Register with
