Data transfer apparatus and method for use in a data processing system.

摘要

A data processing system having a first logical device capable of sending and receiving clocked electronic data and a second logical device connected to the first logical device, the second logical device also being capable of sending and receiving clocked electronic data. A controller is connected to the first and second logical devices for controlling data transfer therebetween. The controller includes a clock edge generator and gating logic connected thereto for allowing the first logical device to accept data and the second logical device to send data during a time interval of an odd number of clock edge.
