The term scoreboard was introduced with the first processor with dynamic instruction scheduling, the CDC 6600, produced by Control Data Corporation in 1964: this was the first real ``supercomputer''.

The 6600 had 16 Functional Units (FUs):

• 4 FP units, 7 integer units and 5 memory units.

A revised design, the 7600 had one, pipelined FP adder and one pipelined FP multiplier instead of 4 non-pipelined units. The dynamic instruction scheduling issues are the same.
