For examples this operation execute very slowly:

unsigned char *mem = ... program memory //(16 bits data bus)

unsignde char *vmem = ... video memory //(8 bits data bus)

for (int i=600; --i; )

for (int j=800; --j; )

if (*mem != 0xF7) {

*--vmem = *mem;

mem--;

}

I need to do this cycle about for 25-30 times per second, but really it works only for 5-10 times per second.

How I can speedup this block?
