Separate power island for high performance processor. A multi-processor design is presented in which each of the processors is implemented in separately powered portions of a circuitry (e.g., an integrated circuit). One of the processors can be a main application processor, and another of the processors can be a baseband processor. In addition, the each of the processors can be implemented using different types of circuitry (e.g., one of the processors [such as the main application processor] is implemented using higher performance/higher leakage circuitry that another of the processors [such as the baseband processor]). One of the processors (e.g., main application processor) can be powered down when not needed thereby providing energy/power conservation which can be vital is handheld communication device applications such as wireless handheld communication devices.

Separate power island for high performance processor that reboots to second boot sector

A plurality of baseband clock signals by detecting an interference condition associated with at least one of the plurality of baseband clock signals and by spreading the spectrum of the at least one of the plurality of baseband clock signals when the interference condition is detected.

Radio frequency integrated circuit having frequency dependent noise mitigation with spectrum spreading

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.
