In this lab, we will learn some basic ARM assembly language instructions and LSLS. R6, R4, #10. ; Logical shift left by 10 bits. ; with flags update.Basic Types of ARM Instructions Control Transfer Instructions: Change flow of execution LSL – logical shift by n bits – multiplication by 2n. You can use SP in these ARM instructions but this is deprecated in ARMv6T2 and above. You cannot use PC in instructions with the LSL{S}{cond} Rd, Rm, Rs syntax. ARM instructions that use Rs must not use r15. Thumb instructions must not use r15 or r13. Condition flags. Logical Shift Left. This instruction is a preferred synonym for MOV instructions with shifted register operands. This is just a shortcut for: LSLS r3, r3, r1. This is because in Thumb, the destination and first source registers need to be the same for most Note. LSL #0 is a special case, where the shifter carry out is the old value of the CPSR C flag. The contents of Rm are used directly as the second operand. A We will learn ARM assembly programming at the Instruction set defines the operations that can ADD R0, R1, R2, LSL R3 @ R0:=R1+R2*2R3.
