Problem
(a) Prepare the assembly code sequence for each of the four styles (accumulator, memory-memory, stack, load/store) of machine for the code fragment:
A = B + C;
(b) Determine the number of instruction bytes fetched and data bytes transferred to/from memory for each assembly code sequence. Which architecture is most efficient as calculated by memory traffic? Which architecture is most efficient as measured by code size?

For an 8088 the 2 addresses linked with an 8259A are normally consecutive, and the AO line is associated to the AO pin, but because there are just 8 data pins on the 8259A and the
