March 2020 was the month when all Arm training suddenly had to go virtual. With the outbreak of Covid-19, global lock downs and remote working for all those that could, classroom training from Arm had to adapt and had to do it quickly.
We'd already been…
hello !
i am houssam an electrical engineering student, i am new to this forum and new for ARM processore i want to make my own PLC (programable logic controler), and i need a processore for to build this PLC, i find a lot of type of ARM processore (cortex…
Hi everyone,
I want to start learning microcontrollers and embedded linux? I want to ask what is differene between A, R and M series of ARM microcontroller? Kindly also suggest me a good book to start learning ARM microcontroller? Which board should I…
Hello All,
I am integrating CAN stack, on Spansion S6J3xx series.
I have configured Main clock as Input frequency, configured CAN transceiver IC and called CclPowerOnInit().
Now calling CanTransmit(X_TxHandle), function in a 100ms task, but still no signal…
Hi Experts,
Is there any document on general software guidelines in reducing the cache miss rate in the system for ARMV7 architectures ?
If it is more specific to A/R/M then its great..
good night everyone.
I was talking with some colleagues about Pico and Nano Satellites, as we enter the point which best microcontroller to use this type of equipment, the CubeSat team (www.cubesat.com) uses the MSP430, but the justification presented…
Hi Experts,
How to derive the cache memory requirement for the working of the software ?
I could understand that each of the A/M/R processors have its own applications and build with its own Cache size MPU/MMU configurations but how this is derived with…
Hi Experts,
As the general discussions seen in the community, it would be great if there is a general guidelines on the list of criteria or guidelines involved in the selection of Cortex A/R/M series Processors ?
Rather than application specific some other…
Hi experts!
I want to use ldr/str or ldm/stm to copy memory not aligned 4bytes.
I know their input address should be aligned by 4 bytes.
but is there any solution to use ldr/str or ldm/stm though src or dst isn't aliged 4byte by modifing following code?…
Hi everyone,
I wonder if there is a documentation that explain how to program efficiently on arm cortex-m and arm cortex-r platform?
I found "arm system developer's guide", but i worried it was too "old-fashion" because it only contained upto armv6..…

We are very pleased to announce a new online training topic – Arm Cortex processor behaviors.
This course builds on our series of topics that introduce the A, R, and M profiles of the Arm architecture and is targeted primarily at hardware…
Where can i get a list of all these family of ARM processors and their differences
Hi all,
The new core ARM V8 supports A & R series alone M series are also be released in near future ?
If not why ?

Yesterday in Shanghai, Freescale Semiconductor made a significant announcement to bring their Kinetis EA series of MCUs into the automotive market.
Thus far, ARM’s success in automotive has mainly been with the ARM® Cortex®-A and Cortex…
Originally this blog post was intended to be all-in-one, but I was suggested to split it into smaller parts.
So what I'll do, is that I'll mention the features I'd like in my ARM processor, one at a time, piece by piece.

对于一个ARM微控制器的初学者来说，有时候要找到一些有用的设计参考信息是非常困难的一件事。因为在网上实在有太多资源了，最先遇到的困难可能就是能不能找到一个地方帮助你正确选择一款ARM的处理器 ，目前，主要有两种ARM处理器：

ARM has started what I find an interesting series of presentations giving facts about their products.
Here is the list so far:
ARM系统的软件开发周期可因等待昂贵的开发硬件而延迟。要在当今的市场中保持竞争力，需要加快在完全验证的系统上开发全功能软件的速度。快速模型就是为这个目的而生。它提供高性能，丰富，准确的程序员视角(Programmer's View)模型库，支持最新的ARM IP。基于模型库构建的虚拟平台模型可使软件开发流程在硬件原型面世数月之前就启动，极大的缩短整个系统的开发时间。
