I could not clearly understand the alignment issues present in ARM. Sometimes I get BUS ERROR while running an assembly file but don't know how to resolve it. Some of the doubts:

1. Is it better to store registers pairwise or individually on the stack…

I need to be able to handle long bitfields as effectively as possible. Right now I need up to 64 bits in length.

Are there instructions to set, clear and test individual bits in one cycle available for some of the architectures? Which? Particularly, will…

Hi,

I have two M0 projects.  The first project has only one assembly file startup.s.  The second project has one assembly file and one C file.  When I checked the memory map file of the second project (shown below), there are some extra object codes included…

I need some indications to begin writing a program.

Write a compare routine to compare 64-bits values , using only two instructions.

Thanks for your indications !

Hi, i have just got a cortex-m0(LPC1114) based dev board. I'm reading about the architecture and instructions. My understanding is that it supports most thumb 16-bit instructions and a handful thumb-2 32-bit instructions. If the processor has a 32-bit…
