Abstract
System and method for regulating the servicing of multiple peripheral devices by a central processing unit. The system and method is highly beneficial where some of the peripheral devices place equal priority demand on the central processing unit. A plurality of link interfaces are interconnected between the peripheral devices and the central processing unit. The link interfaces are interconnected by means of token transmission circuitry. The token transmission circuitry requlates the operation of the link interfaces and thereby the serving of the peripheral devices. The use of the token transmission circuitry substantially increases the efficiency and performance of the link interfaces.
