Chapter 5.4, Problem 5.3PP
Program Plan Intro
Memory aliasing:
- It denotes a case where two pointers might designate to memory location that is same.
- The compiler should assume that unlike pointers might be aliased for safe optimizations.
- The program aspects that could limit chances for a compiler in generating optimized code denote optimization blockers.
- If a compiler is unable to determine whether two pointers might be aliased, it should adopt that either case would be possible.
- The possible optimization set is been limited in this case.
Cycles per element (CPE):
- The CPE denotes performance of program that helps in improving code.
- It helps to understand detailed level loop performance for an iterative program.
- It is appropriate for programs that use a repetitive computation.
- The processor’s activity sequencing is controlled by a clock that provides regular signal of some frequency.

- Problem 17. [ 1 point for correctness ] Use the Design Recipe to define a function pulse_rate that has two parameters. The first is the number of seconds a nurse has counted pulses, and the second is the number of pulses counted (both ints). The function should return the pulse rate, pulses/minute, as a float. Don't forget to convert seconds to minutes! Include a Docstring.(use Python) For example: Test Result print(round(pulse_rate(30,22),1)) 44.0 Use this statement to test your pulse_rate function: assert_equal(round(pulse_rate(30, 22),1),44.0)arrow_forwardENGINEERING • COMPUTER-ENGINEERING 2 - calculate the first four iterations for the approximate value of the root of the function f(x) = x*log(x) - 1 using the method below: a) Bissection Method.
