ABSTRACT:
A data buffer is connected to the first and second processor and the first processor sends a start signal to the second processor, which responds to the start signal by reading data from a data source, such as an input/output device, and then writes the read out data into the data buffer. After conclusion of the writing operation, the second processor sends an end signal to the first processor which is admitted to start sending data stored in the buffer to a host processor after receipt of the start signal. The start signal and the end signal are provided to the second processor and the first processor respectively, after passing through a synchronizing circuit.
