NOTE: explain the lines in comments for better understanding Write an assembly program (for x86 processors - Irvine) that has two procedures, a main procedure and a procedure called Fib. The fib procedure is to uses a loop to calculate and printout the first N Fibonacci numbers. Fibonacci sequence is described by the following formula: Fib(1) = 1, Fib(2) = 1, Fib(n) = Fib(n – 1) + Fib(n – 2). The value of N is to be communicated to this...
