           近期不少新的国产平板方案开始陆续登场“亮分”,相信很快,基于新的国产芯片方案的平板产品要量产铺货了。但是可惜,这些新的方案的跑分无一例外没有跑安兔兔X版本的(防作弊)。
      笔者虽然确信新一代国产芯片肯定比原来老芯片性能有很大提升,跑分也很亮眼,但是选择性无视安兔兔X版本,也同时让笔者对真实效能越来越云里雾里。貌似雷军现在也不更新这个分支了,估计当时打击华为啥的达到目的,但是后来发现自己也不能“优化”跑分了…

    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。
