[General] Embedded Assembly language versus Embedded c language

[sudheer kumar]

Hello guys,

I have a doubt, I am new to ARM and need to learn architecture and in depth of ARM.
For this I am going through "ARM reference guide", book- but people explained on Assembly, not C. Even many books follow the Assembly, Why?

I am working on C but doesn't no assembly.

My question is why people explain it with ASSEMBLY? and is it necessary to learn Assembly? How to link this to Embedded C?

Assembly gives you a register level view of how the processor works. It helps learn the architecture.

A book about ARM will have to cover topics specific to ARM, and there is nothing ARM-specific in C.
You don't need to learn assembly-language to program a microcontroller , but it will help in the long run.
By that, I mean that you will eventually need to make something run faster or require less memory; knowing the details will help.
