If there are 32-bit instructions, that means there are 2^32 total values these instructions could have. If addresses are 12 bits, each 2-address instruction has 2^24 values it could have. So...

For example, suppose you have a function
int f(int n) {
if (n == 0) {
return 1;
}
else {
return n * f(n-1);
}
}
We want to measure its cost. But before we do so, we'll...
