Dual FIFO peripheral with combinatorial logic circuitry

摘要

An adapter is connected between a peripheral controller and an intelligent peripheral device. The adapter allows the peripheral device to communicate with the controller. The adapter has control logic rather than a microprocessor for transmitting and receiving data. The control logic is comprised of combinatorial logic circuitry and a command register. The command register allows the controller to configure the cominatorial logic circuitry in order to control adapter operation.
