摘要：
A system (15) comprising at least two integrated processors (P1 and P2). These two processors (P1 and P2) are operably connected via a communication channel (17) for exchanging information. One processor (P1) has a processor bus (10), a shareable unit (13), and a DMA unit (11) with an external DMA channel (12). The DMA unit (11) and the sharable unit (13) are connected to the processor bus (10). The other processor (P2) has an access unit (21) which is a connectable to the external DMA channel (12) of the DMA unit (11). Due to this arrangement, a communication channel (17) can be established from the access unit (21) which is connectable to the external DMA channel (12), the DMA unit (11), and the processor bus (10).
