Abstract
A method for allocating bus access rights is used in a multimaster bus system wherein addresses are explicitly allocated to master devices and each master device is assigned a priority value from an organized priority list of priority values. Requests from at least one master device to use the bus system to access a slave device are received, and the priority values of all requesting master devices are compared. If a sole requesting master device has the highest priority value access to the respective slave device is granted to that master device. If a plurality of requesting master devices have the same highest priority value access is successively granted to the requesting master devices having the same highest priority value on the basis of the address allocation of the master devices.
