An asymmetric digital subscriber loop modem may achieve efficiency and cost reduction by providing a coder/decoder (codec) chip which transmits data externally of the chip when the data is at a reduced or lower data rate. That is, instead of transmitting the data at a higher data rate, which may result in increased cost, for example for EMI shielding, the codec chip transmits the data when the data is at a reduced data rate.

Asymmetric digital subscriber loop modem

A communications and networking riser includes a plurality of riser codecs and an adaptive initialization module coupled to the riser codecs. The initialization module configures the riser codecs when the riser is connected to a motherboard having a codec controller and a primary codec. The initialization module automatically selects between a two-codec configuration and a three-codec configuration based on a codec support capability of the codec controller.

Method for control of codecs in PC riser card architectures

A riser card with a corresponding interface on a motherboard can reduce the overall cost of an electronic system as well as simplify upgrading the features provided by the riser. Implementation costs can be reduced, for example, for audio components that may otherwise require shielding in order to prevent electromagnetic interference if the audio component were located on the motherboard. Other components can also be simplified if located on a riser rather than the motherboard. Upgrading of features supported by the riser card is simplified because the riser card can be replaced. The riser card described herein provides Plug-and-Play functionality so that an operating system controlling the electronic system in which the riser card is included can load the appropriate driver software thereby simplifying operation of the electronic system.

Motherboard extension features to provide plug and play information

A method and device are provided for managing a group of electrical devices, e.g., coder/decoders (codecs) in a computer system, including enabling and disabling a primary electrical device. An address ID module assigns a primary address to designate one of the devices as a primary device. The primary device performs certain functions that are only performed by a single device. Other devices are designated as secondary devices. A signal control circuit receives a BIOS-controlled signal as an input, and outputs a presence signal indicating whether the original primary electrical device is enabled or disabled. If the original primary device is disabled, the address ID module designates one of the secondary devices as the new primary device, and the other secondary devices remain secondary. The new primary device performs certain functions of the original primary device.

Method and apparatus for BIOS control of electrical device address/identification assignments

A riser card with an interface on a motherboard can reduce the overall cost of an electronic system as well as simplify upgrading the features provided by the riser. Implementation costs can be reduced for components that may otherwise require shielding in order to prevent electromagnetic interference if the component were located on the motherboard. Other components can also be simplified if located on a riser rather than the motherboard. The riser card described herein provides functionality so that an operating system controlling the riser card can load the appropriate driver software thereby simplifying operation of the electronic system. In one embodiment, a BIOS stored in a memory on the motherboard interacts with a memory on the riser card to obtain information related to functionality of the riser card and to properly initialize the components of the riser card.

Basic input/output integration of motherboard extension features and plug and play information delivery

A method and device are provided for managing a group of electrical devices, e.g., coder/decoders (codecs) in a computer system. Members of a group of electrical devices may be located on the motherboard of the computer system, or off the motherboard, such as on a riser card. An address ID module assigns a primary address to designate one of the devices as a primary device. The primary device performs certain functions that are only performed by a single device. Other devices are designated as secondary devices. A signal indicates whether a member of the group of electrical devices is located on the motherboard. If no device is located on the motherboard, the address ID module designates a primary device and secondary devices from among the devices located on the riser card. A routing module routes output signals from the devices to input pins of a controller. If a device is located on the motherboard, it is designated as the primary device by the address ID module, and the other devices are designated secondary devices. A routing module shifts the routing of the output signals from the secondary devices to different pins on the controller.
