摘要
The method involves transferring data between an initiator and a responding equipment, both coupled to the bus, by outputting a data request signal from the initiator and a response signal with a reservation identifier from the responding equipment if it is able to accept the request but too busy to respond immediately. The identifier is output again when the responding equipment is ready. The method involves transferring data between an initiator and a responding equipment, both coupled to the bus, by outputting a data request signal from the initiator requesting permission to use the bus for data transfer, generating and outputting response signal and a reservation identifier from the responding equipment coinciding with the initiator requesting data if the responding equipment is able to accept the request but is too busy to respond immediately, outputting the reservation identifier again when the responding equipment is ready, preparing for the data from the initiator as soon as it has is received the identifier and initiating data transfer when the initiator is ready. Independent claims are also included for the following: a bus system and a bus-compatible initiator.
