摘要：Apparatus is described for enabling a first processor to cause a secondprocessor to effect a transfer of data between the processors in accordance with data
transfer commands sent from the first processor to the second processor. Theprocessors each have a program instruction memory for enabling the processors tooperate independently and simultaneously when no data transfer is occurring betweenthem. The apparatus comprises data transfer circuitry connected between the processorsfor enabling the data to be transferred. A program instruction decoder is associated withthe second processor for normally decoding and executing instructions stored in theprogram instruction memory of the second processor when no data transfer is occurring.Routing circuitry carries the data transfer commands from the first processor to theprogram instruction decoder for decoding and executing to provide signals to the datatransfer circuitry to effect a transfer of data.
