Abstract
A data communication system comprising a system processor, an application program assigned to an application buffer it controls, a communication protocol program assigned to a protocol buffer it controls, a communication controller for controlling communication lines, and transmitting and receiving buffers controlled by the communication controller. Data is copied at high speed among the application buffer, protocol buffer, and transmitting and receiving buffers in the same byte-based increments as those in which the system processor handles data. The fast data movement among the buffers boosts the throughput of the entire communication system.
