The study found that both at home and abroad, the current situation of support tools mostly in three ways, namely: the website or project site, The virtual simulation software, Special courseware.

综合国内外的研究现状发现，当前的探究支撑工具大多以三种方式，也即：网站或专题网站；虚拟仿真软件；专题课件。

Many research institutions have invested a lot of energy, but due to geographical constraints and other factors, the simulation software has become a more actual research tools than network deployed.

许多研究机构投入了大量的精力，但是由于地理等因素的制约，软件仿真成了比部署网络试验更为实际的研究手段。

With a comprehensive set of ARM and ARM partner development tools and simulation models already available to enable faster and easier software development, both processors are fully compatible with the extensive ARM 32-bit ecosystem and integral to the rapidly evolving ARM 64-bit ecosystem.

ENGADGET: ARM's Cortex-A50 chips promise 3x performance of current superphones by 2014, throw in 64-bit for good measure
