Answer to Question #162892 in C++ for Task

Question

A smartwatch is a very useful device developed by several companies these days including Apple, Samsung, Motorola and several others. It has a touch screen interface providing features like GPS tracking, heart rate and sleep monitoring etc. with power efficient batteries. The ARM Cortex processors are used in smartwatches providing several benefits.

 

Suppose we have to choose between ARM Cortex-A or Cortex-M series architecture for our next generation smartwatch. Which one would you select between the two and why? Support your selection of either architecture with solid reasoning considering memory management, cost, performance and chip size

Answer 1

I will use cortex A inbuilt device, the reason for the selection are listed below-

Architecture of the cortex A device:

• It is based on application processors.
• It is used in the wide range devices which have fully functional processors.
• The performance, computational power and the efficiency is very high of cortex A.
• The running frequency of this processors is very high.
• It requires large amount of energy.
• It can handles large amount of applications and it is capable of running complex operating system.
• It is used in the telephones, tablets and laptop etc.

Architecture of cortex M device:

• It is based on the micro-controller devices.
• It is designed for the small devices and mixed signal processing.
• The performance point for these devices are less but the efficiency is very high.
• The clock speed of this devices are slower.
• It requires less memory.
• It is developed into the micro controller with the input and output line and designed for the small factor system which relay on the heavy digital input and output.
• It requires the less energy but the battery efficiency is very high.
• It is used in the robotic devices, small consumer electronic devices.
