Abstract
A serial bus control apparatus is disclosed. The apparatus includes a device for providing a reservation control table for reserving a transmission bandwidth and a transmission channel used at a future time on a serial bus. The reservation control table is organized such that transmission of data of certain bandwidth and channel at a certain future time can be reserved for a transmission between arbitrary nodes. The reservation control table is stored and controlled on a first register. The register is accessible for reading and writing from an arbitrary node on the serial bus. The apparatus may further include a detection part to detect present time and a second and third register for securing available transmission bandwidth and channel at present time. By having this reservation control table, it becomes possible for each node on the serial bus to secure transmission of data of certain bandwidth and transmission channel in a desired future time.
