Abstract
An endpoint control apparatus for a device communicating between a host and plural endpoints by way of a universal serial bus includes pluralities of buffers corresponding to the plural endpoints, a first storage unit having data storage status information of the buffers, a controller allocating an empty one of the buffers to a selected one of the endpoints in response to the data storage status information, and a second storage unit having a result of the buffer allocation.
Claims18
An endpoint control apparatus for a device communicating between a host and a plurality of endpoints by way of a universal serial bus, the apparatus comprising:
- pluralities of buffers corresponding to the plurality of endpoints;
- a first storage unit having data storage status information of the buffers;
- a controller allocating an empty one of the plurality of buffers to a selected one of the endpoints in response to the data storage status information;
- and
- a second storage unit having a result of the buffer allocation by the controller.
A method of controlling endpoints for a device communicating between a host and the endpoints by way of a universal serial bus, the method comprising:
- receiving a write-in/read-out request for a selected endpoint;
- conducting the requested write-in/read-out operation by means of a buffer allocated to the endpoint;
- updating data storage status information of the buffer;
- and allocating a write-in/read-out buffer to the selected endpoint, for the write-in/read-out operation, in response to the data status information.
