Reduced testcase for the first one:
static unsigned short int crc_table[256];
void AC3_encode_init(void)
{
unsigned int c, n, k;
for(n=0; n<256; n++)
{
c = n << 8;
for (k = 0; k < 8; k++)
{
if (c & (1 << 15))
c = ((c << 1) & 0xffff) ^ (((1 << 0) | (1 << 2) | (1 << 15) | (1 << 16)) & 0xffff);
}
crc_table[n] = c;
}
}
