选择微控制器的 10 个步骤
原作者：jacobbeningo 原文地址： 10 Steps to Selecting a Microcontroller
翻译一篇文章，他山之石，可以攻玉。以下为正文：
为产品选择正确的微控制器可能是项令人怯步的任务。您不仅要思考许多技术特性，还要考虑成本和备货时间等会削弱项目的业务方面问题。在项目初期，您会有立即动手的冲动，想要在商定系统的细节之前开始选择微控制器。这当然是糟糕的想法。在对微控制器进行任何思考之前，硬件和软件工程师应当先制定出系统的高水平规格，画好框图和流程图，只有这时才有充足的信息对微控制器选择做出理性的决定…
双口ram读数据的速度太慢
系统结构与功能：
lpc3131外接8k*8双口ram与8G Flash，从双口ram读取数据（来自FPGA），并存至Flash中。
问题：
丢数据，系统速度远低于ram的读速与Flash的写速度。
双口ram读数据直接采用指针，如下：

arm 汇编 dcb指令
Error : armlink: L6204: Entry point (0x00008000) does not point to an instruction.这个错误的产生，我觉得是我用了dcb指令，放在了程序的开头，它开辟了一个连续的存储空间，都是用来放数据的，所以无法找到指令。然后就有了一个新的问题，这个dcb指令，以及其他的内存分配指令，应该怎样使用，他们在程序中的位置应该在哪，比如说我像开辟一个以字节为单位的连续存储空间用来存放abcdef，应该把它放在哪里，放在程序中间感觉不太合适…

助力芯片定制化趋势，推动智能互联发展
大众创业万众创新成为了2015年我听到的最多的宣传声音，从各种大大小小的设计研讨会/智能硬件设计竞赛，到形形色色的产业孵化器，政府也调动各种资源对此推波助澜。表面繁荣的背后，不可忽视的一个痛点就是当你作为一个初创公司有了一个很好的创意，不管你是通过众筹抑或天使投资终于把产品做出来并推向市场后，可能很快你就会不幸的发现你的产品被别人抄袭了。而且这种抄袭并不是简单意义上的外形/功能抄袭，甚至芯片里面的控制程序都被别人用很小的代价就可以逆向得到。这不得不说是我们市场上的一个悲哀，也是众多创业者的无奈。也就是说在物联网的时代…
