Abstract
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.
