  • STRD ATOMIC?

    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…

  • Trying to find basic performance measurements of ARM cores

    Howdy, I was trying to find some basic performance benchmarks for a couple of different ARM cores: The Arm 926EJ-S, Cortex A9, and the Cortex M7.

    I am looking for primarily DMIPS (per MHz or a form that requires me scaling to my specific chip is fine…

  • 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…
