METHOD FOR ACCESSING TO A DATA TRANSMISSION BUS, CORRESPONDING DEVICE AND SYSTEM

摘要

The invention relates to a bus (10) which is connectable to a primary master (22) and to secondary masters (32) and is used for transmitting data between peripherals. In order to ensure a minimum rate and/or maximum latency between the secondary masters when the primary master uses a small time fraction available on the bus, said primary master is provided with a high priority and comprises means for wirelessly accessing to a medium. The inventive method for accessing to the bus consists in authorising the primary master to access to the bus upon the request thereof and in selecting the access to the buss for the secondary master when the primary master peripheral does not request said access to the bus.
