ARRANGEMENT WITH MASTER AND SLAVE UNITS

摘要

The arrangement has a master unit connected to slave units via a bus. Each slave unit has an associated memory to which the master unit has read and/or write access. Each slave unit has a protocol region (1,2) via which the master unit indicates to the slave unit a desired access. - The slave unit uses this protocol region to grant or refuse access. In the event of access being granted the master unit assigns a memory address region whose position (adr30) it reads from the protocol region.
