In contrast, Motorola chose to ignore this approach and designed an entirely new concept not based on compiler design. The idea was that they would not attempt to compete with the ever-growing list of similar RISC designs on the market, instead, they would produce the world's most powerful processor. To do this, they took design notes from one of the fastest computers of the era, the CDC Cyber supercomputer, notably using its concept of a scoreboard, which was used as it was in the CDC machines to aid instruction dispatch, but also as a way to improve subroutine call performance.
