汇编比C语言更节省空间吗？（内面内容值得探讨，欢迎行家发表意见）

我在学校时刚开始用汇编，但后来老师说用C更方便，更好。我就顶着头皮有C，后来觉得C太好了。但现在出来工作，我是在家电公司格兰仕工作，但他们都在用汇编。因为他们说汇编节省空间，他们一般在家电方面的单片机空间只有4~6K，此类的MCU价格一般不超过大概5块钱。几乎家电业都是如此。我想问下，像这么4K的汇编代码用C来写大约要多少空间呢？

还有一个问题就是请问行家：有没有5~10块钱的ATMEL公司生产的单片机呢？此类的单片机有多大的空间呢？

望大家踊跃的探讨啊？我不想以后也想他们的现在软件工程师一样写4000多行的汇编代码啊？

怎么没有人说话啊/

自己顶了！

iloveuyh 发表于 2006-10-12 22:26:12

答案是肯定的, 很明显！

有个分水岭,对51来说就是4K,4K以下程序用汇编省时,比这多且经常要升级或修改,C的好处就发挥出来了.

5~10块钱的ATMEL公司生产的单片机

mega48mega8 ,邮购部的信息查询一下就知道了

家电的产品里面的控制芯片都是用最便宜的,呵呵

neutronlmk 发表于 2006-10-13 08:27:02

小家电类很多还在用4bit的单片机，像我现在主要的工作就是这个....

这么小的空间当然用汇编方便，而且我用的根本没有c编译器。

avr-qq 发表于 2006-10-13 15:19:26

of course

lixu 发表于 2006-10-17 18:27:00

哎！汇编的代码好痛苦啊！主要是重复性太厉害！搞死人啊！

怎么没有那位行家高手客观的分析分析啊？

我觉得C语言是将来发展的趋势，不知道对不对？

bg6agb 发表于 2006-10-17 18:45:03

我觉得

不太会用的人用C好,上手快,考虑的问题少

会用的人用汇编好,对所用的东西都能一把掌控,

比会用的人再厉害点的也是用C好,能用C把所用的东西都掌控在手,需要很多技巧

最厉害的是两个混着用,能根据实际情况分别对待,能扬长避短

个人看法,欢迎拍砖

用c写一个带有参数和局部变量的小程序然后在main中调用，avrstudio调试，查看其disassembler 仔细看一下编译器生成的汇编，参数和局部变量都保存在了堆栈中，其实我们在做汇编的时候也可以借鉴这种思路，照搬当然是不行的那样会浪费很多的处理器时间和寄存器根据这个思想自己设计一套程序的设计规范，自己用着舒服也方便移植别人的程序

汇编复杂很多时候就是复杂在变量，寄存器，参数传递等的协调和处理上，好好解决一下这个问题很有用

slamkk 发表于 2006-10-18 20:56:23

8楼说得很有道理！

watercat 发表于 2006-10-19 07:23:13

该用汇编的地方用汇编，没必要用汇编的地方都用C，但无论如何，都应该把汇编部分和C部分从文件上区分开来

狭义的“两个混着用”，恰好是最差的编程习惯

lixu 发表于 2006-10-19 21:15:27

我在学习中颖和三星的单片机，现在漫漫的对那些几千行的汇编代码没有那么陌生了。觉得汇编不弄懂，根本上谈不上说学会了单片机，当然你不一定要用汇编。不信去问问马老师是怎么说的，我觉得很有道理。

我不知道有论坛有没有人在用中颖和三星的单片机，大家来讨论讨论交流啊！！！

不知道有没有人对汇编感兴趣，有的话，我就传一个上来大家谈论。

sonic 发表于 2006-10-19 22:33:03

你这的这二款单片机很少人用的，你上传一个汇编的，可能能看懂的人不会很多的！

johnnypang 发表于 2006-10-19 22:43:16

对于TINY13这类只有1k的容量，用C很难实现的项目，使用汇编，还能剩1/3的空间。

但对于大项目，汇编的生产效率就明显低了。

优势可以互补的。

lixu 发表于 2006-10-20 19:58:49

今天我特意问了一下，我问他们工程师们为什么不用51系列的单片机，得到的答复是：51的抗干扰性差。

而难道用什么SAMSUNG，NTK，TOSHIBA，他们的价格和抗干扰性以及可靠性就真的很好吗？

谁能回答这个问题？

传一段中颖单片机的程序上来，汇编的高手来指教指教，如果有人肯发表高论，那我就全部帖出来了。

例外有没有高手和老手可以说说现在市面上单片机，各个厂家的每个型号的单片机在那一个领域最有

优势。这样我们也可以整体提高大家的成本意识。

这是一段家电控制上的汇编源程序，大家就悠着点看吧！眼睛痛不要找我啊！呵呵……

补充说明一点，是中颖的四位机，价格很便宜不超过4RMB。

中颖的指令少，简单，66之后性能已经够用，我也在用。

ares_lan 发表于 2006-10-21 11:25:28

各有优劣。我不知道你们那行都写些什么样的程序。人不可能总是面对一种类型的工作。要是用习惯了C，写汇编就会不习惯了。但我还是觉得用C好些，可能是自已的方向决定的。另外，芯片的价格越来越低，空间越来越大，这是趋势。很多功能强大的芯片不一定用得到。倒是很老的型号，可以实现功能的，又低价的，现在倒不为首选了。呵呵。

JAMESKING 发表于 2007-3-22 15:46:58

对于AVR的Mega16，我做过这样的对比：

M16的汇编语言我照抄了《AVR单片机实用程序设计》的一些内容，那本书上汇编语言写得不错，同样实现一个功能，我采用汇编和fastavr编写，结果很有意思，居然无论执行速度还是代码效率，avrasm和fastavr都几乎一样，而后来学了一点点cvavr，又编写了一个类似的测试程序，发现代码长度有大幅度下降，下降可达50%，而执行速度也有所提高，平均提高30%左右，经过观察三者的asm输出，发现如下事实：

1。如果c语言不优化，代码长度与代码执行效率与通常的basic和asm差不多；

2。如果c语言优化合适，则无论代码长度还是执行效率比basic都要好；

3。basic优化和不优化一个样子；

4。如果不采用宏汇编和宏定义，只采用基本汇编语言，那么汇编语言的执行效率与代码长度同basic区别不大

5。c语言优化以后的代码和未优化的代码，都大量调用宏汇编和宏定义，这也是c语言能够比基本汇编语言代码长度和执行效率都要好的最关键之处，而avr的basic，我所知道的有三种，都没有这样调用宏汇编命令和宏定义。

代码的问题，仁者见仁智者见智，不能以偏概全。

【16楼】 lixu贴出来的程序，以及《AVR单片机实用程序设计》里面的所有程序，都是基本汇编语言，不是宏汇编语言。

另外据确认，我国单兵火箭筒上面的简易火控系统采用的是基本汇编语言编写的，并没用到宏汇编。而很多进口重型机械，比如现在开挖隧道使用的盾构机，其部分控制系统也采用的是基本汇编语言所写，MC68HC908的。

我从不认为哪种语言会有优势，除非是同样的语言类型而产生了很不同的效果（这在basic里面存在，Mikrobasicavr比bascom和fastavr代码长度大一倍，都是basic），编译语言是为系统服务的，能完成系统指标，就是个好语言。

benladn911 发表于 2007-3-22 15:55:03

JAMESKING 兄说得极是。

呵呵，我觉得适用就好。

JAMESKING 发表于 2007-3-23 00:28:20

抱歉，下午看花眼了，15楼的程序应该说是“部分宏汇编”，比C语言里面纯粹调用宏语句还是有些差别的，但不管怎么说，宏汇编确实能有效缩短代码长度，我觉得宏汇编似乎是以时间换取空间的优化。

我个人的偏好喜欢使用基本汇编语言，而且对控制速度没有过分的要求，所以似乎一些basic编译器也能满足要求。

另外，avr还有梯形图编译器，可以直接用梯形图编译代码，直接输出HEX文件，虽然还不是很完善，但也很有意思。

TonyCai 发表于 2007-3-23 00:59:06

我是先学汇编，在学C，很长时间就用汇编，后来慢慢转用C，想想以前都是些小东西，用汇编没有觉得可读性的问题，现在打死我也要C，习惯了，

xiaobendan 发表于 2007-3-23 08:04:52

我用过T13，就几片而已，就是用的GCC，使用了800字节的HEX。程序很简单，2个输入，2个输出而已。那么几个脚能做什么复杂的东西呢？

david1234 发表于 2007-3-23 08:48:37

汇编是靠人脑优化的，C是由电脑优化的。

电脑相同，人脑有差异。量力而行。

yu_bo 发表于 2007-3-23 09:08:40

抱歉, 我一直以为宏汇编就是在基本的汇编指令中加入宏, 也就是把一些常用的小代码断用宏来替代.当然也可以是复杂的循环. 宏的展开最终是用代码替代的, 并不能起到减少代码的作用.

如果说汇编在执行速度和代码长度上与中高级语言没有优势的话, 我真不知道它的存在还有什么意义了.

ThinkCell 发表于 2007-3-23 13:05:41

家电行业的量都是非常大的，动不动就是500K采购，1000K的采购，如果一颗芯片可以省下一毛钱的话，500K可以节约5万块，1000K可以节约10万块。如果把节约的钱奖给开发人员20％，大家会有多高兴啊。

家电里的MCU都比较小，而且是ROM的居多。由于偏移所以很多搞家电的工程师都会三星、飞斯卡尔、瑞萨、合泰、富士通等。我们以前还用中颖的4位机，现在想想也是市场竞争太激烈没办法啊。好好研究MCU汇编指令，用汇编确实可以压缩大量得程序空间。

不过汇编的程序移植性太差，时间长了程序就忘了，得重新读。如果没有备注就倒霉了。

我现在把程序全部改成C，遇到新产品开发时，项目进展速度就快很多。

【16楼】 lixu贴的是中颖的汇编，我也在用中颖的芯片，因为没用多久不敢有太多的评价。我觉得对于内存跨页的芯片，最好把内存和页标志一起定义在头文件中，这样就算以后跨区调配内存也不需要很麻烦。

joson 发表于 2007-3-23 16:02:04

家电行业就是这样，价格竞争太厉害。以前还在家电公司的时候，用三星9228编了一个程序，用C弄的，出货也出了几十万了吧，后来客户增加功能，还要成本下调，只能更换芯片，又把汇编拿起来了。而且，小家电行业里面的程序都不是很复杂，没有烦人的数据结构，汇编已经能够搞定，处于成本考虑，何必用C呢。

所以说，在家电行业，很多时候都在和成本打交道，郁闷，这不，自己就跑出来了。

xiejun 发表于 2007-3-24 15:07:02

其实都是成本在作怪，做事的是我们，谁不喜欢容易的C呀，但是现实与实际总是有差距的。如果8K的ROM空间和2K的ROM的单片机价格相等的话，我想大家都会用C，除非你对速度和时序有明显的要求。

vivalite 发表于 2008-2-16 06:58:05

很多低档4位机程序通过烧内部熔丝的办法存储下来，这样做稳定性比Flash高，价格又比Flash的低，小家电行业老板都喜欢呀。

Edesigner 发表于 2008-2-16 09:43:34

用汇编的原因可能是因为没有找到好的编译器吧。就像合泰，听说支持它的Ｃ编译器不多，效果不太好。但如果用pic我会用picc不用汇编，就算是12c508.

xuhai777 发表于 2008-2-16 10:05:51

用汇编最烦没有好的汇编器
如果汇编器能增加局部标号和局部变量功能，那么我认为它就是好的汇编器了，我会选择汇编而不是C
像AVR的avrasm32.exe不支持上述两点
而WIN32的很多汇编器（如masm）就支持上述两点

oouu01 发表于 2008-2-17 20:45:18

这其实是个哲学命题：
汇编毕竟比C更“原始”。好比修房子，以前就是用砖块垒。现在的楼房都是钢筋水泥的搭框架，把房屋支撑的受力、压强、结构和屋面防水室内装潢分开来做。更系统化，特别是对于大系统来说。比如几十层的高楼用砖一直垒上去就很悬。如果只是修点小房子，一时间又找不到更好的建材那么用砖头当然是经济之选。

希望以后大家都能用上更高级的语言，一般这样描述的：“小X（或者X工）！你来负责YY项目的代码编写”

gxlujd 发表于 2008-2-17 21:07:57

我觉得开发时间与程序空间历来都是互斥的关系，至于想要什么要自己考虑了。

yinyan186 发表于 2008-2-19 15:12:39

合泰自带的IDE3000就可以直接编译C。
小家电行业里面基本上都是用一些低成本的芯片，台系的就很多人用啊，像HT，中颖，易隆等，比起来AVR的价格是偏高了些的。
但如果，这个产品的附加值高，能接收这个芯片上的差价，当然原意用AVR这些芯片啦。

Feeling_MCU 发表于 2008-2-19 16:04:44

我51汇编算是初级水平吧，汇编也有宏定义，就像15楼贴的前半段都是宏定义，这样可以提高程序的可读性和更清晰的安排变量的存储空间。

其实只要入门一种单片机的汇编，其他的也就不是很难了，汇编有两个技术含量高的地方：一个是合理分配数据的存储和寄存空间，一个是用汇编来实现以及优化比较复杂的算法。

bobo21 发表于 2008-4-9 13:59:12

用C吧，用汇编的话，写得头都大都写不出来。

gdutxzy 发表于 2011-5-27 13:45:18

我用汇编的，程序空间只有500行，也就是0.5K,用汇编200行就够了，不过同事用的是C，但编译后也就300到400行的样子，
所以你写C的时候注意一下结构，不会说不够用的。

sc88cs 发表于 2011-5-27 14:27:06

学校时用汇编，现在工作了就用C。
还是C好啊。
写了5000多行的C
如果用汇编会跳楼。

tootzoe 发表于 2011-5-27 15:31:26

去年年度我也干样的事情, PIC 芯片 32K flash,另一个同事用汇编写了 1.6万的行的代码, 我后来改用C写, 写了5千多行代码,高度优化,勉强够空间, 吐血好几次才完成....我真不知道那个同事这汇编代码是怎么熬出来的....

380121850 发表于 2011-5-27 17:33:36

不一定的，说汇编比C空间少，那是理论情况下的
因为实际情况是：使用汇编，7、8K的代码的时候，重复代码会有很多，而且很多在C常用的算法，像加减乘除，都要自己再写，而且写出来的代码不一定高效。。。。。
两种情况下，汇编会少：
1、一个超级牛人汇编
2、程序简单
3、给足够时间，对完成的代码进行足够的优化
但是，一般情况，下，只有2成立。。。。

深有同感！大学时候就是汇编很顺手，就是变量空间不好协调，程序稍微复杂点，就不知道怎么用汇编了
后来切换到c，就再也不想汇编了
那时候，一直想学混合编程，苦于没有好的案例工参考学习
