METODO PER TRASFERIRE DATI IN UN CIRCUITO ELETTRONICO, CIRCUITO ELETTRONICO E DISPOSITIVO RELATIVO

The present invention is related to a method of transferring data in an electronic circuit (10) incorporating a control unit or CPU (21), first circuit blocks (41) and second circuit blocks (61) interconnected by means of a BUS (24). The method and the relating circuit envisage the use of interface devices (45a) and/or (45b), associated to respective circuit blocks, and capable of managing the direct transfer of data from the first block (41) to the second block (61), or vice-versa, without the control by the CPU (21) during such a transfer. For the purpose of this method, and relating circuit (101), interface device (45a) must be, able to intercept control commands issued by CPU (21) and to directly manage the data transfer from the first block (41) to the second block (61) .Thus, the method and the circuit (101), and the interface device (45a) make it possible to considerably reduce the load of CPU 21, BUS 24 and electronic circuit (101) as well.
