AI summary

A single chip wireless transceiver operable to perform voice, data and radio frequency (RF) processing is provided. This processing may be divided between various processing modules. This single chip includes a processing module having an ARM microprocessor and a digital signal processor (DSP), an RF section, and an interface module. The processing module converts an outbound voice signal into an outbound voice symbol stream, converts an inbound voice symbol stream into an inbound voice signal, converts outbound data into an outbound data symbol stream, and converts an inbound data symbol stream into inbound data. These functions may be divided between the ARM microprocessor and DSP, where the DSP supports physically layer type applications and the ARM microprocessor supports higher layer applications. Further bifurcation may be based on voice applications, data applications, and/or RF control. The RF section converts an inbound RF voice signal into the inbound voice symbol stream, converts the outbound voice symbol stream into an outbound RF voice signal, converts an inbound RF data signal into the inbound data symbol stream, and converts the outbound data symbol stream into an outbound RF data signal. The interface module provides coupling between the processing module, the RF section, and with off-chip circuits.
