ABSTRACT:
An apparatus and method of assigning communication channels for transmitting data through a host bridge are provided. In a preferred embodiment, a determination is made as to whether data is being transmitted through any one of the channels. If data is not being transmitted through one the channels, that channel is designated as the transmission channel for the present data transaction. If data is being transmitted through all of the channels, a least most recently used channel is selected as the data transmission channel. If however, more than one channel is not transmitting data, the data transmission channel assignments are made among the idle channels from a lowest channel number (e.g., channel 0) to a highest channel number (e.g., channel 7) or vice versa.
