Method and the device for the data transmission which leads AC-97 protocol link

摘要

In order to do data communication in parallel with the AC97 protocol device and the non AC97 protocol device, the audio encoder/the decoder (AC) it can use 97 protocol links. In order to decide, tag data 502 inside the AC97 data frame, CODEC203 of specification, selecting 204, and 205, ignores which data time slot, receives which data time slot it is used. In order for tag data to use only one of 502 and other data frame time slot, to utilize 11 slots telephoney communication and vis-a-vis the communication which uses the non AC97 protocol device in parallel it is possible telephone sound and data communication. The Ethernet (R), the foam/home phone line network alliance (HPNA), attachment interface (AUI), it is several of the data communication protocol which can be used by the occasion where execution example of this invention is used. Modifying AC97 data communication controller 201 with further logic and the control line, it is possible to support the further quality of the non AC97 protocol device.
