Convert binary unsigned vector to dec list
- by Juan
This code convert a unsigned long vector variable cR1 to NB_ERRORS numbers (in 'a' variable I print these numbers).
for (l = 0; l < NB_ERRORS; ++l) {
k = (l * EXT_DEGREE) / BIT_SIZE_OF_LONG;
j = (l * EXT_DEGREE) % BIT_SIZE_OF_LONG;
a = cR1[k] >> j;
if(j + EXT_DEGREE > BIT_SIZE_OF_LONG)
a ^= cR1[k + 1] << (BIT_SIZE_OF_LONG - j);
a &= ((1 << EXT_DEGREE) - 1);
printf("\na=%d\n",a);
}
For example I am have a cR1 with two elements that follow:
0,0,1,1,0,1,0,0,0,0,1,0,0,1,1,1,1,1,0,0,1,1,1,1,0,0,0,1,1,0,0,0,1,0,1,1,0,0,1,0,1,1,1,0,0,1,0,0,1,0,1,0,1,1,1,0,1,0,0,1,1,1,1,0, executing that code I get (44), (228, (243), (24), (77), (39), (117), (121). This code convert from right to left, I want modify to convert from right to left, Where I will be able to modify this?
pdta: In the example case EXT_DEGREE = 8, BIT_SIZE_OF_LONG = 32
