Multi-mode cellular IC for multi-mode communications
First Claim
1. A radio frequency (RF) integrated circuit (IC) comprises:
- a signal receiving section operably coupled to;
convert a cellular data inbound RF signal into a cellular data inbound symbol stream;
obtain a wireless local area network (WLAN) inbound symbol stream;
an audio codec operable to convert an output digital signal into an output voice signal;
a bus matrix operably coupled to the audio codec; and
a processing unit operably coupled to the signal receiving section and the bus matrix, wherein the processing unit is operable to;
convert the cellular data inbound symbol stream into a first voice over internet protocol (VoIP) signal;
convert the WLAN inbound symbol stream into a second VoIP signal; and
facilitate providing, via the bus matrix, at least one of the first and second VoIP signals to the audio codec as the output digital signal.

Abstract
An RFIC includes an RF section, a memory interface, a display interface, an audio codec, a bus matrix, and a processing unit. The RF section converts a first inbound RF signal into a first inbound symbol stream and converts a second inbound RF signal into a second inbound symbol stream. The memory interface is operably coupled to retrieve a video file from memory and the display interface is operable to provide video data to a display. The audio codec converts an output digital signal into an output voice signal. The processing unit converts the first inbound symbol stream into streaming video data; converts the second inbound symbol stream into the output digital signal; and facilitates providing, via the bus matrix, at least one of: the video file to the display interface as the video data; the streaming video data to the display interface as the video data; and the digital output signal to the audio codec.
