Purpose of this Lab
This lab is designed to explore the use of inline assembler, and its use in open source software.
This lab is designed to explore the use of inline assembler, and its use in open source software.
Lab 7
References
Part A - Class Lab
1. Write a version of the Volume Scaling solution from the Algorithm Selection Lab for AArch64 that uses the SQDMULH or SQRDMULH instructions via inline assembler.
2. Test the performance of your solution and compare it to your previous solution(s).
3. Blog about your results in detail, including your reflections.
Part B - Individual Task
After Memory Architecture
Do this part of the lab after the class on Memory Architecture.

2. Find the assembler in that software, and determine:
- How much assembley-language code is present
- Which platform(s) it is used on
- Why it is there (what it does)
- What happens on other platforms
- Your opinion of the value of the assembler code VS the loss of portability/increase in complexity of the code.
3. Blog your results in detail.
