METHOD FOR TRANSMITTING SAMPLED DATA AND CONTROL INFORMATION BETWEEN A DSP AND AN RF/ANALOG FRONT-END

摘要

A method for delivering control information together with sampled data between a DSP and an RF/analog front-end in a high speed communication modem, which embeds sampled data and control information in frames to be transferred over one interface. A frame may comprise various fields, each may consist of one or more bytes or octets. The frame may have a data field for carrying the sampled data, and at least one control field for transferring the control information to update RF/analog front-end registers. The control field may include an octet containing a control address, an octet containing a control command, and an octet containing control data. The frame may also provide means of synchronization, e.g., by using a sync field to identify the frame boundary.
