Abstract:
1. A dynamic voltage scaling system for a packet-based data communication transceiver communicating via communication packets, comprising: a constant voltage supply configured to supply a constant voltage to at least one parameter-independent function of the transceiver, wherein parameter-independent transceiver functions perform operations independent of a predetermined parameter, the predetermined parameter being attributes associated with the communication packets; a variable voltage supply configured to supply a variable voltage in accordance with a control signal to at least one parameter-dependent function of the transceiver, wherein parameter-dependent transceiver functions perform operations dependent on the predetermined parameter; and a voltage control unit configured to generate the control signal based on information about the predetermined parameter provided by at least one parameter-independent transceiver function, wherein the parameter-independent transceiver function operates on a preamble portion of a communication packet and includes a synchronization function.
