Question

3a) Mathematically, what does the following snippet of RTL code do to the value stored in R1? In other words, if the contents of R1 are interpreted as a number, write a relationship between the values before and after this code executes. Ignore cases that overflow. Simplify your answer as much as possible. R2 = R1 OR 0 R2 = R2 SLA 2 R1 = R2-R1 3b) What would the result (in R1) be if the initial value (in R1) was 3010? What would the result be if the initial value was -3010?
