out an important problem with the traditional "more is better" approach; even those instructions that were critical to overall performance were being delayed by their trip through the microcode. If the microcode was removed, the programs would run faster. And since the microcode ultimately took a complex instruction and broke it into steps, there was no reason the compiler could not do this instead. These studies suggested that, even with no other changes, one could make a chip with fewer transistors that would run faster. In the original RISC-I
