现在写了一个函数，是一个480*640的二重循环，处理图象的
按F10单部运行的时候经常跑飞掉，然后提示Illegal opcode (xxxxxxxx) at pc = yyyyyyyy，xxxxxxxx是yyyyyyyy地址处的操作码，用Mixed ASM/Source查看，发现此处的汇编语句变成了 .word xxxxxxxx
不知道这个语句是干什么的，总之到了这里就出错了
我的编译选项完全没有修改，保持了 -g ，没有选择 -oN（N=1,2,3）

该函数代码如下
void GaussianFilter3x3
(
WORD pR1[ ][IMAGEWIDTH],
WORD pG1[ ][IMAGEWIDTH],
WORD pB1[ ][IMAGEWIDTH],
WORD WR1[ ][IMAGEWIDTH],
WORD WG1[ ][IMAGEWIDTH],
WORD WB1[ ][IMAGEWIDTH]
)
{
volatile int i,j;
unsigned int temp;
for(j=1;j<479;j++)
for(i=1;i<639;i++ )
{
//if(pR1[j] == 0)// skip暗点
if(pR1[j] < MIN)
{
continue;
}
else
{
temp
=
pR1[j-1][i-1]*Table_Gau3x3[0][0]
+pR1[j-1]*Table_Gau3x3[0][1]
+pR1[j-1][i+1]*Table_Gau3x3[0][2]
+pR1[j][i-1]*Table_Gau3x3[1][0]
+pR1[j]*Table_Gau3x3[1][1]
+pR1[j][i+1]*Table_Gau3x3[1][2]
+pR1[j+1][i-1]*Table_Gau3x3[2][0]
+pR1[j+1]*Table_Gau3x3[2][1]
+pR1[j+1][i+1]*Table_Gau3x3[2][2];
WR1[j]=temp>>16;
temp
=
pG1[j-1][i-1]*Table_Gau3x3[0][0]
+pG1[j-1]*Table_Gau3x3[0][1]
+pG1[j-1][i+1]*Table_Gau3x3[0][2]
+pG1[j][i-1]*Table_Gau3x3[1][0]
+pG1[j]*Table_Gau3x3[1][1]
+pG1[j][i+1]*Table_Gau3x3[1][2]
+pG1[j+1][i-1]*Table_Gau3x3[2][0]
+pG1[j+1]*Table_Gau3x3[2][1]
+pG1[j+1][i+1]*Table_Gau3x3[2][2];
WG1[j]=temp>>16;
temp
=
pB1[j-1][i-1]*Table_Gau3x3[0][0]
+pB1[j-1]*Table_Gau3x3[0][1]
+pB1[j-1][i+1]*Table_Gau3x3[0][2]
+pB1[j][i-1]*Table_Gau3x3[1][0]
+pB1[j]*Table_Gau3x3[1][1]
+pB1[j][i+1]*Table_Gau3x3[1][2]
+pB1[j+1][i-1]*Table_Gau3x3[2][0]
+pB1[j+1]*Table_Gau3x3[2][1]
+pB1[j+1][i+1]*Table_Gau3x3[2][2];
WB1[j]=temp>>16;
}
}
}
就是一个3×3的Gaussian滤波器，请各位大侠帮助看一下吧，卡了好几天了啊 |
