Problems solved by technology

[0003] The voice chip in the home gateway mainly converts the analog voice signal into a digital voice signal, and connects the voice DSP chip through the PCM interface, so as to realize the VOIP (Voice overIP) phone. The SLIC chip is essential in the home gateway. Voice chips need to develop the voice chip driver separately, and integrate the driver code into the Soc (System On Chip) software system of the main chip of the home gateway for commissioning. Different types of voice chips need application programs and drivers. Adaptation and development work, the chip driver interface functions cannot be unified, and the voice software version is unified

Abstract

The invention discloses a household gateway voice chip identification and voice software loading system and method and relates to the computer and communication technology field. Unified voice chip interfaces are utilized to fit driving API interfaces in different chip types of different voice chip manufacturers or different chip factories, an integration problem of voice chips provided by the different manufacturers existing in a household gateway is solved, and development cost is effectively reduced. The method is advantaged in that automatic voice chip type identification and automatic voice software loading are realized, each function interface of the voice chips are integrated into a unified voice chip common interface function, the unified voice chip common interface function is provided for upper-level applications to call a voice chip function, so the upper-level applications are rapidly transplanted to different product modes of the household gateway through the unified voicechip common interface function.

Description

technical field [0001] The invention relates to the technical fields of computer and communication, in particular to a voice chip recognition and voice software loading system and method in a home gateway. Background technique [0002] The home gateway refers to an application device in the home network with an intelligent operating system; through the home gateway, it can not only access the Internet, but also access the phone through the voice chip SLIC (Subscriber Line Interface Circuit) of the home gateway. It is a multifunctional intelligent terminal that can connect to the network, connect an external USB disk through the USB port, and insert various SD cards through the card slot. [0003] The voice chip in the home gateway mainly converts the analog voice signal into a digital voice signal, and connects the voice DSP chip through the PCM interface, so as to realize the VOIP (Voice overIP) phone. The SLIC chip is essential in the home gateway. Voice chips need to dev...
