After the microprogram is finalized, and extensively tested, it is sometimes used as the input to a computer program that constructs logic to produce the same data.
This program is similar to those used to optimize a [[PLDProgrammable logic device|programmable logic array]].
No known computer program can produce optimal logic, but even pretty good logic can vastly reduce the number of transistors from the number required for a ROM control store.
This reduces the cost and power used by a CPU.
