A radio frequency integrated circuit (RFIC) includes a low noise amplifier that amplifies an inbound radio frequency (RF) signal to produce an amplified RF signal. A down conversion module converts the amplified RF signal to a down converted signal based on a local oscillation. An analog to digital conversion (ADC) module coupled to convert the down converted signal into a digital signal. A baseband processing module converts the digital signal into inbound data, wherein at least one function of the baseband processing module is clocked by a plurality of baseband clock signals A clock module produces the plurality of baseband clock signals, wherein the clock module detects an interference condition when frequency dependent noise components associated with at least one of the plurality of baseband clock signals are inside a frequency band associated with the inbound RF signal, and spreads the spectrum of the at least one of the plurality of baseband clock signals when the interference condition is detected.

A processor within a wireless terminal performs data compression, decompression and error correction according to a data compression protocol such as the V.42bis data compression protocol used within GSM wireless networks. This processor includes an interface that receives incoming information or data to be compressed or decompressed according to the data compression protocol. A processing module within the processor is operably coupled to the interface to receive and process the incoming information. Instructions executed within the processing module will divide the processing responsibilities between the processing module and a data compression/decompression accelerator operably coupled to the processing module. Compute intensive operations may be offloaded from the processing module onto the data compression/decompression accelerator to improve overall system efficiency.
