Abstract
Methods and apparatuses are provided for establishing operational states of a device having a plurality of functional operating units. An input is configured to receive an identifier of a desired operational state of the device. A number of control outputs are configured to couple to one or more of the plurality of functional operating units having two or more operational states. A number of reference inputs are each configured to receive a reference signal, and at least one reference signal is mapped, based on the identifier, to at least one control output. Each control output provides a control signal that places each functional operating unit in a selected state to achieve the desired operational state of the device.
Claims20
A configurable controller for establishing desired operational modes of a device having a plurality of functional operating units, the controller comprising:
- an input configured to receive an identifier of a desired operational mode of the device;
- a plurality of reference inputs, each reference input being configured to receive a reference signal, the reference signal being pre-configured to have one of a first value and a second value based on the desired operational mode of the device;
- and
- a plurality of control outputs, each control output being mapped to one reference input of the plurality of reference inputs based on the identifier, each control output being coupled to one or more of the functional operating units and configured to provide a control signal that places the one or more functional operating units in a selected operating state of at least two operating states to achieve the desired operational mode of the device.
A configurable controller for establishing desired operational modes of device having a number of control lines, comprising:
- a plurality of reference inputs configured to receive a reference signal, the reference signal being pre-configured to have one of a first value and a second value based on a desired operational mode of the device;
- a plurality of multiplexers corresponding in number to the number of control lines, each multiplexer configured to provide a control signal to one of the control lines based upon the reference signal received at a selected reference input;
- and
- a control input to receive an identifier of the desired operational mode of the device, the control input coupled to each of the plurality of multiplexers to select the selected reference inputs based on the identifier.
A method of making a controller for a device having a plurality of control lines, comprising:
- selecting an m-to-1 multiplexer, where m is greater than or equal to a number of desired operational modes of the device;
- replicating, within the controller, the m-to-1 multiplexer k times, where k is a number of control lines in the plurality of control lines;
- configuring, a reference source external to the controller to provide m input reference signals to the controller for each m-to-1 multiplexer based on the desired operational modes of the device;
- and
- providing the m-to-1 multiplexers in a group configured to control the electronic device.
A method of controlling desired operational modes of a device having a plurality of control lines, comprising:
- receiving an identifier that identifies a desired operational mode of the device;
- selecting a reference signal from among a plurality of reference signals based upon the identifier, the reference signal having a pre-configured value that is one of a first value and a second value based on the desired operational mode of the device;
- and
- providing a control signal to one of the control lines based upon the selected reference signal.
