对于ARM体系来说，不同语言撰写的函数之间相互调用（mix calls）遵循的是 ATPCS（ARM-Thumb Procedure Call Standard），ATPCS主要是定义了函数呼叫时参数的传递规则以及如何从函数返回，关于ATPCS的详细内容可以查看ADS1.2 Online Books ——Developer Guide的2.1节。这篇文档要讲的是汇编代码中对C函数调用时如何进行参数的传递以及如何从C函数正确返回,ARM system for example, written in

Power sector is one of the key sectors contributing significantly to the growth of country’s economy. Power sector needs a more useful role to be played in defining, formulating and implementing the research projects with close involvement of all

4. 16QAM uses a mix of amplitudes and phases to achieve 4 bits/Hz. In this example, there are three amplitudes and 12 phase shifts. While QAM is enormously efficient of spectrum, it is more difficult to demodulate in the presence of noise, wh
