Abstract
A method of and apparatus for communicating between a host and an agent. The method includes the step of performing a first transaction between a host controller and a hub. The hub is operable to perform a single transaction with an agent based on the first transaction. The method then includes the step of performing a second transaction between the host controller and the hub. The second transaction is based on the single transaction.
Claims20
A device comprising:
- a camera;
- a controller hub coupled to the camera, wherein the controller hub is to:
- receive a start split transaction at a high speed to indicate a beginning of a transfer;
- send a token to the camera at a low-speed, wherein the token includes a transfer type and a data rate identification;
- and
- receive data from the camera, wherein the controller hub is to include a buffer to buffer the data received from the camera until after a speed shift from the low-speed to the high-speed is performed.

A system comprising:
- a game machine including a plurality of digital devices to be in communication, wherein a particular digital device of the plurality of digital devices comprises a camera and a controller hub, the controller hub comprising:
- an upstream port to receive a start split transaction at a high speed and data;
- and
- a buffer to buffer the data to be received at the upstream port until after a speed shift from the high speed to a low-speed, wherein a token is sent to the camera at the low-speed and the token includes a transfer type and a data rate identification.
1 more element
A controller hub comprising:
- an upstream port that is capable to send and receive a start split transaction and to operate at a high speed, wherein the start split transaction is to indicate a beginning of a transfer;
- a downstream port that is capable to transmit an in token, to receive an out token, and to receive data, wherein the downstream port that is capable to operate at a low-speed, wherein the in token includes a transfer type and a data rate identification;
- and
- a buffer to buffer the data from the upstream port and the downstream port and perform a speed conversion from the low-speed to the high-speed.
