1、(1)32bit乘法的指令解释
(2)volume1的load.asm基础上实现一个
16bit数组的乘法累加的函数,并进行 -o2 / -o3 / 手工优化
2、c环境
C调用汇编函数,汇编函数调用c函数
addarr3(int * arr1, int * arr2, int * arr3, int * arr4, n)
//汇编函数,3个数组的对应位置相加,结果放在arr4[n]中,
汇编函数调用C的子函数,它把arr1和arr2相加放到arr3

用C51实现的拼音输入法,这是改写的网友 embuffalo、独步上载在www.21ic.com自由发布区的由张凯原作的51上的拼音输入法程序。
原作使用了一个二维数组用以查表,我认为这样比较的浪费空间,而且每个字表的索引地址要手工输入,效率不高。所以我用结构体将其改写了一下。就是大家现在看到的这个。
因为代码比较的大,共有6,000多汉字,这样就得要12,000 byte来存放GB内码,所以也是没办法的 :-(
编译结果约为3000h,因为大部分是索引表,代码优化几乎无效。

优化如下:
1、结合论坛大家的程序,去粗取精。
2、大家的程序都是在单片机开一个128bit数组,存储显示数据,一方面占用了单片机的宝贵空间,而且,每次改变一个段位,都要把全部数据写一遍,比较占用时间。
3、采用对所写段位先读后写的方式,每次只读写4bit,对数字位,只读写8bit,提高速度。
4、程序在89s52单片机运行通过,程序中加了详细注解,便于阅读。
5、编译后的空间占用由论坛的程序的1200字节降到800字节,降低1/3.-Optimization is
