Abstract
According to one exemplary embodiment, a host/client system includes a host module, which includes a CPU coupled to a system bridge. The host/client system further includes at least one client having an integrated interface, where the integrated interface is coupled to the system bridge through a scalable serial bus. The system bridge and the integrated interface enable high bandwidth communication between the CPU and the at least one client through the scalable serial bus, thereby allowing control of bus width between the host module and the client.
Claims9
A host/client system comprising:
- a system bridge;
- a host module including a CPU coupled to the system bridge;
- a scalable serial bus coupled to the system bridge;
- and
- first and second clients, each having an integrated interface, the second client being coupled to the first client via the scalable serial bus and the first client being coupled to the system bridge via the scalable serial bus;
- wherein the integrated interface of the first client is configured to:
- receive a communication from the CPU over the scalable serial bus,
- determine whether the communication is intended for the first client, and, if so, to send the communication to an instruction layer of the first client, and
- determine whether the communication is intended for the second client and, if so, to send the communication to the second client via the scalable serial bus.
