Forcing circuitry: Sequential building blocks for logical design

The performance of an entire computer system is greatly influenced by the elements that are chosen for its sequential logic. For example, the central processing unit of the IBM (International Business Machines Corporation) 704 was organized around the Haven´s delay unit chosen for its storage, accumulator, and M-Q registers. As machines having more parallel operation and increasingly complicated controls are developed, a greater percentage of the machine is composed of sequential devices. It thus becomes more important to consider the logical capabilities of the circuits which are chosen.
