Data processing instructions in arm

WebASR provides the signed value of the contents of a register divided by a power of two. It copies the sign bit into vacated bit positions on the left. LSL provides the value of a register multiplied by a power of two. LSR provides the unsigned value of a register divided by a variable power of two. Both instructions insert zeros into the vacated bit positions. http://csbio.unc.edu/mcmillan/Comp411F18/Lecture07.pdf

Data Processing Instructions - Introduction to the ARM

WebThese instructions test the value in a register against Operand2. They update the condition flags on the result, but do not place the result in any register. The TST instruction performs a bitwise AND operation on the value in Rn and the value of Operand2. This is the same as a ANDS instruction, except that the result is discarded. WebARM data processing instructions can be broken into four basic groups: Arithmetic (6) Logic (4) Comparison (4) Register transfer (2) We haven’t discussed the “S” field yet.
