Hi, Sorry if this is a long thread but i'm really confused.
I program for AVR MCUs and also know about Arduino, I can program for different ATMEL MCUs with looking at datasheets, And i also programmed a few basic stuff on Cortex-M3 LPC1768, without…
as we know supervisor mode is priviliged and user is not. at reset time in debugging mode, i read the cpsr it is 0x1d3 means in supervisor mode, so i can change CPSR so i changed it to 0x1d0 which is user mode, since user mode is unpriviliged so i must…
Hi, I make a software for Cortex-A9 and Cortex-M4 (both uni-processor system).
Question.
Is 64bit-aligned STRD(64bit memory access) atomic ?
(I know tha It is not atomic, but i don't know behavior.)
For example:
LDR R2,=buff
mov R0, #1
mov R1, #2
STRD R0…

Paul Beckmann received his BS…
In the spirit of some of the more well-known ARM-based development boards and their popular communities, I was curious what other innovative ideas are out there being crowdsourced. Just a bit of research quickly revealed eight ARM-based embedded projects…
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。
