Chapter 5.6, Problem 5.4PP
A.
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.

We can program in both Java and Python, and we have the choice of using three different computers with different instruction set architectures: x86, ARM, and MIPS. Regarding microarchitecture, for x86 we have two choices, and for ARM and MIPS we have three choices for each of them. How many choices we have to run a sort algorithm? (Draw diagram).arrow_forward
- For this task we are going to use ENet architecture. You can read the description in the original paper. To generate two different outputs we need to have two different branches. In the LaneNet paper authers proposed to share only two first sections of the encoder between to tasks. Third section and decoder should be separate for the instance segmentation and binary segmentation problem.
