And station, bus interface for use bus system, the bus system

摘要

The present invention relates to a bus system and a second station, which is connected to the first station, a bus for transferring signals. The bus is configured to operate according to a protocol that sends the first station are repeatedly toward the second station a request for data. This protocol, because the first mode to transfer by the communication speed of the first in the request format of the first requests them to transfer at a second speed in the request format of the second request are including the mode of at least a second. The second station is configured to receive in one mode selected from a mode of the group including the mode of the first and second requests, further, for the first station, it is the first give an indication of the first when it is configured to operate according to the mode, configured to provide an indication of the second when it is configured such that it operates according to the second mode. In accordance with the present invention, the first station comprises a processor, a controller and a translator. Processor is operable to create at the request format of the first request property for those requests. Controller is operable to create at the request format of the first requests from these requests these properties. Furthermore, if the first indicator is detected, if it is sent to the second station in a first format requests these second indicator is detected, the controller, the translator requests are and is operable to transfer. The translator is also operable to transmit to the second station in a second format, the request thereof.
