摘要： An apparatus for reducing modem command and status latency within a direct access arrangement (DAA) circuit is disclosed. The DAA circuit includes a serial audio interface for providing communications between the DAA circuit and the host computer system. The serial audio interface can operate under multiple serial communication interface standards, such as the AC '97 standard and the HD Audio standard. The DAA circuit also includes means for configuring the serial audio interface to transmit and receive modem samples at an audio sample rate higher than a modem sample rate of the modem samples and at a predetermined bit size that is wider than a bit size of the modem samples. The additional bits other than the modem samples are utilized to indicate command and status information associated with the DAA circuit or a telephone line such that modem command and status latency on the serial audio interface within the DAA circuit can be reduced.

摘要： An integrated circuit device and associated method are disclosed utilizing on-chip programmable circuitry that receives and stores vendor identification information, in particular, for devices meeting operational requirements of the Audio CODEC '97 Component Specification. The programmable circuitry allows for vendor ID information for multiple device configurations and/or multiple vendor supplied devices to be accurately reported to external devices. In particular, direct-access-arrangement (DAA) circuitry is disclosed having such on-chip programmable circuitry that may be loaded with vendor identification information at least in part from an external source. The external source may in turn be programmable circuitry, such as a EEPROM. This disclosed invention allows a single hardware DAA solution to be utilized by different software vendors, who each add their own respective software functionality, and to be utilized by a single software vendor, who desires to bundle different software functionality or revisions with the single hardware DAA solution. In this way, an integrated circuit may be designed and manufactured to provide a single hardware solution for a variety of different software or other programmable configurations.

摘要： Programmable on-chip identification circuitry and associated method are disclosed that provide integrated circuits with the ability to select and report from multiple different vendor and system identification configurations. The integrated circuit device includes programmable circuitry that utilizes vendor identification, system identification, configuration or other device information provided or selected at least in part based upon selection information from a source external to the integrated circuit. The selection information may be provided through one or more externally generated digital and/or analog control signals that are then processed within the integrated circuit device to select, access and utilize desired identification information stored in an on-chip database. For example, one or more analog control signals can be generated using resistor circuits for which specific selectable resistor configurations map to particular information stored in a look-up table or other database structure within the integrated circuit. The analog control signals are converted to digital values within the integrated circuit, and these digital values are used to select device information from the on-chip database. Furthermore, the selected device information can be stored in on-chip device information registers. And the digital values themselves can be stored and used as identification, configuration or other device information.

摘要： A start circuit controlled by an electronic control unit for providing power from one or both of a battery and TRU in parallel to a starter motor coupled to a gas turbine engine. The circuit includes contactors between the TRU and battery and a junction where the current from the TRU and battery combine. The circuit further includes two additional contactors in series between the junction and the starter motor. Voltage sensors and contactor position sensors are employed for diagnostics. A novel method of starting the engine using the start circuit contemplated by the present invention is also descibed. In this method, the start is initiated with power only from the battery. After a period of time power from the TRU is added. This method reduces the amplitude of the start motor inrush current, which has a beneficial reliability effect on the components of the start circuit.
