How to avoid overflow in expr. A * B - C * D
...and performing the multiplication as below:
(R1 + R2 * 2^32 + R3 * 2^64 + R4 * 2^96) = R = A*B = (A1 + A2 * 2^32) * (B1 + B2 * 2^32)
R1 = (A1*B1) % 2^32
R2 = ((A1*B1) / 2^32 + (A1*B2) % 2^32 + (A2*B1) % 2^32) % 2^32
R3 = (((A1*B1) / 2^32 + (A1*B2) % 2^32 + (A2*B1) % 2^32) / 2^32 + (A1*B2) / 2^32 +...

To get the columns from C to E (note that unlike integer slicing, 'E' is included in the columns):
df.loc[:, 'C':'E']
Out:

What is the direction of stack growth in most modern systems?
...m memory, they may not be totally correct.
For example, if R3 was the PC, R4 was the SCRT call address, R5 was the SCRT return address and R2 was the "stack" (quotes as it's implemented in software), SEP R4 would set R4 to be the PC and start running the SCRT call code.
It would then store R3 on t...
