Due 4/8/97
Write the micro-code to perform the following calculations:
1)
-
Add the contents of memory location 100 to the contents of memory location 101
If the result is < 0 then
store the result in memory location 100
else
store the result in memory location 101
Assume that register A contains the value 100.
-
Consider the following C++ program fragment:
int x=SOME_NUMBER; // SOME_NUMBER has been #defined... int *xptr; xptr = &x;Assume the xptr variable is stored at memory location 1000
Then the contents of memory location 1000 will be the memory address of the variable x.
Write micro-code to perform the following operation:
-
If x > 0 then
Register B = X + 1
else
Register B = X - 1
Assume that register A contains the value 1000
