    Hello,

    Consider following scenario:

    1. A 4 KB page starting @0x80000000 is marked as Normal Memory, Inner Cacheable, write-back, non-shareable, non-outer cacheable, L2 is inclusive cache.
    2. Now, the s/w writes to the first word in the page. Let's assume valid…

    Hi,

    We found the following document on Cortex-A9 performance.

    List of ARM microarchitectures - Wikipedia, the free encyclopedia

    Which claims 2.5 DMIPS/MHz per core for Cortex-A9 2GHz@2 core. However, our Dhrystone result on Cortex-A9 1.2GHz@2 core only showed…

    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…
