WebShift Instruction The ARM has two shift instructions: arithmetic shift and logical shift. An arithmetic shift can right-shift a number by up to 32 bit positions, and the sign bit is placed in all vacated bits. A logical shift can shift right (LSR) or left (LSL) up to 32 bits, and a ‘0’ will be placed in all vacated bits. Web5 May 2015 · Instruction timings - arm cortex m3.
