Abstract

A disc intercommunication system is disclosed for use in a data processing system and provides a communication path (218) which interconnects all the programmable disc devices (212-214) in a multi- processor system. The disc devices (212-214) use their self-contained processor (220) and memory (221) to interpret data transfer commands and thereby determine which disc devices are to be involved in the data file transfer. The disc devices (212-214) communicate among themselves directly via the communication path (218) to accomplish the data file transfer thereby saving considerable overhead in the host processors. <IMAGE>
