Circuit device for interfacing between several processing units equipped with microprocessors.

摘要

The invention is directed to the field of control electronic devices and in particular relates to a circuit device for interfacing between several processing units equipped with microprocessors which consist essentially of a control unit (2) connected to serial ports and to parallel ports (3,4,6,7), and a memory (4) relative to the control circuit and an interface (9) for a RAM memory (10), in such a way as, when two different processors are connected through such device, it is possible make the processors to operate, even if of different structure, by exploiting said RAM memory as a connection element, usable in a fashion type multiplexed multiport and/or of type circular queue, FIFO, LIFO: said RAM memory i.e. appears configurable at will, depending on processors to be interfaced. <IMAGE>
