The table above shows the speed for each class of instruction. Note that many of the instructions have

multiple opcodes. There are 255 opcodes for 111 instructions. Of the 255 opcodes, 159 are three times

faster than the original 80C32. While a system that emphasizes those instructions will see the most

improvement, the large total number that receive a 3 to 1 improvement assure a dramatic speed increase

for any system. The speed improvement summary is provided below.
