The invention relates to an addressing scheme for doubling the transmission capacity of a master-controlled slave-to-slave communication in any kind of bus system which makes it possible to transmit data from one slave to a second slave on a bus within a bus cycle controlled by a bus master. This is achieved simply by way of a special address assignment so that the invention can be used with any address-controlled bus system, such as PCI, ISA, EPP. The description distinguishes between indirect read access, inverse indirect read access and indirect write access as variants of the addressing scheme. These three variants differ in terms of the direction of transmission between the participating slaves a and b and the hardware required for implementation. Normal bus access remains possible without restrictions. |
