ABSTRACT:
A data transfer apparatus for use in transferring data frames between a data buffer and an input/out (I/O) device in a data processing system. A channel in the data processing system includes an inbound frame header buffer for storing a header from an inbound data frame from the I/O device, an outbound frame header buffer for building a header for an outbound data frame to be sent to the I/O device, a data buffer for storing data transmitted between the data processing system and the I/O device, and a data transfer control circuit for controlling the number of data bytes to be transferred between the data buffer and the I/O device. The channel also includes a microcode routine controlled microprocessor for analyzing frame headers in the inbound frame header buffer, for building frame headers in the outbound frame header buffer, for initiating the transmission of outbound frames, and for controlling the data transfer control circuit for transferring a desired number of data bytes.
