I don't really know if this is the sub to ask this, if it isn't, i'll remove the post (sorry in advance :) ) I have to do an assigment for class, creating a routine on arm5 assembly that multiplies two numbers and checks if there is an overflow (the format of the numbers is signed Q12). It should return (by r0) 0 if there isn't overflow and 1 if there is. This code is form last year's solution of a fellow student, and i was just reviewing it bc, ngl, i'm pretty lost. But i do not understand anything. Why the lsr and lsl to the low part of the result of the multiplication? why comparing it ..read more

I am interested in learning about ARM embedded development, in pure C. I have a Raspberry Pi Zero W, and an Arduino R4 WiFi, which are both ARM based. Would these be good starting points to to studying this topic? Which one of these two do you think would be more useful, difficult, easier, well documented, etc. Please tell me your opinions, thank you :) submitted by /u/5calV [visit reddit] [comments ..read more

Hi there, looking for a hardware recommendation for board / case etc for a home-built NVMe only NAS Requirements: ARM-based, power efficient, no hardware-intensive tasks needed, something at the level or above a Raspberry 5 must run a standard linux distribution and some docker containers 4x NVMe (more is fine) + eMMC or internal NVMe for OS decent build quality, good looking case, quiet optional: PoE powered, 60W can be delivered by my switch price is not an issue Looking forward to your recommendations. I looked at the new UGREEN NASync which has a nice x86-bases model with the ..read more

New to ARM, and don't know what is best. I am looking to find an open source ARM interpreter that I can use and manipulate. I am trying to build a symbolic execution engine for ARM, but don't know where to begin looking other than finding random githubs. Anyone have any suggestions? submitted by /u/wjfi [visit reddit] [comments ..read more

Is the most powerful ARM ITX(or micro-atx) board with pcie and UEFI support still the Coretex A72? Why can't other companies make ARM like Apple? Can I wait some board with Qualcomm? submitted by /u/colaH16 [visit reddit] [comments ..read more

Hi! I am searching for an ARM laptop and cant find the one for me. Why do I want ARM? I am interested in the architecture and absolutely want the long battery life. It should be 14 inch, have 4-8 GiB of RAM, preferably 8. It needs to be able to handle running stuff like Pulsar-edit or VScode, Firefox, and spotify at the same time without lag. I want to use it with either armbian or endeavourOS-arm. It should also have functioning bluetooth and wifi with these linux distros. Do you have a recommendation? submitted by /u/5calV [visit reddit] [comments ..read more
