ABSTRACT:
An apparatus for controlling the transfer of data between a first remote processor constructed to process data words of a first length and a second remote processor constructed to process data words of a second length and which includes a storage member constructed to store data words of a third length. A DMA controller controls the transmission of data words between the storage member and the first remote processor. A first control processor controls the operation of a second processor and the DMA controller for transferring data from the second remote processor to the storage member. In response to instructions transmitted from the second remote processor, the first control processor will enable the second control processor to transfer data words of a third length to the storage member and will enable the DMA controller to transfer data words of the second length from the storage member to the second remote processor. Logic circuit means under the control of the first control processor enables either the first or second control processor or the DMA controller access to the storage member for performing a read or write operation on the storage member.
