help on NRF51822

[julien.launay]

Hello,

I'm a teacher.
I use the microbit card that loads one of your components. Nordic nRF51822-QFAA-R rev 3
Could you tell me if this processor is based on a Von Neumann type architecture?

I am looking for a very simple IDE to program in assembly your processor on the microbit card.
Would you have a very simple IDE to advise me.
I am trying to show the difference between a very simple program in assembler and the same program written in C. EN show the difference in assembler coding between the two solutions.
Could you confirm that the computer world no longer uses the assembly language, because the high-level language complier is good enough and optimizes the code.
Thank you very much for your very precise help. Do not hesitate to ask for help from your engineers in order to provide me with a very precise help.
Your sincerely.

Hi Julien, 

Could you tell me if this processor is based on a Von Neumann type architecture?

The processor inside of Nordic nRF51822-QFAA-R is ARM Cortex-M0 CPU which is Neumann type architecture.

 

Would you have a very simple IDE to advise me.

This post might help you.

 Though it's true, you probably won't find yourself writing your next customer's app in assembly, there is still much to gain from learning assembly.
Today, assembly language is used primarily for direct hardware manipulation, access to specialized processor instructions, or to address critical performance issues. Typical uses are device drivers, low-level embedded systems, and real-time systems.
Assembly language is as close to the processor as you can get as a programmer so a well designed algorithm is blazing -- assembly is great for speed optimization. It's all about performance and efficiency. Assembly language gives you complete control over the system's resources. Much like an assembly line, you write code to push single values into registers, deal with memory addresses directly to retrieve values or pointers. (source: codeproject.com)
