  • in arm7tdmi, when FIQ and RIQ occures at same time so how both are executed sequentially,first FIQ and thenIRQ?

    in arm7tdmi, suppose instruction is being executed and at same time FIQ and IRQ both occur  at same time.now according to priority FIQ will be handled then IRQ  but my question is that how it will handled IRQ after  return from FIQ

  • Cortex-A8 performance

    I'm working an a project on a Texas Instruments AM3517 Cortex-A8 processor. I was seeing less than expected performance, and did a simple comparison with a Cortex-M3 processor. The M3 performance was more than twice as good as the A8(?!).

    The test…

  • Help me jump into ARM world !(I know nothing but AVR)

    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…

  • How to learn ARM

    Hi everyone!!

    I am looking to work on some projects using ARM. I have completed a basic course on ARM M3/M4 (UT Austin 6.01x by Jon Valvano and Ramesh Yerraballi) online. Now, I want to learn advanced things, especially real-time applications. How should…

  • What is TrustZone for ARMv8-M?

    As a product manager for the Cortex-M33, I see this question pop up a lot. Below is my version of the answer.

    Characteristics of TrustZone technology

    • TrustZone is the security foundation for billions of ARM Cortex-A processor-based systems

  • Eight innovative ARM-based Kickstarter projects

    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…

  • Fast Models (快速模型) 简介

    概况

    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。


    关键特性

    • 功能准确的ARM指令集模型，被集成进ARM处理器硬件开发流程中进行对比验证
    • 支持ARM多项先进技术，包括高速缓存(Cache…
