<p>A data processing system includes a plurality of nodes (501-504), a serial data bus (50) interconnecting the nodes in series in a closed loop for passing address and data information, and at least one processing node (501). In one construction, this processing node (501) has a processor (510), a printed circuit board (500), a memory partitioned into first and second sections and a local bus (13) connecting the processor (510), a block sharable memory section of the memory, and the printed circuit board (500). The local bus (13) is used for transferring data in parallel from the processor (510) to a directly sharable memory (518) section of the memory on the printed circuit board. The printed circuit board (500) includes a sensor for sensing when data is transferred into the directly sharable memory (518), a queuing device for queuing the sensed data, a serializer (32) for serializing the queued data, a transmitter for transmitting the serialized data onto the serial data bus to the next sussessive processing node (501), a receiver for receiving serialized data from next preceding processing node (501), and a deserializer (31) for deserializing the received serialized data into parallel data.</p> |
