Abstract

A baseband controller includes a microsequencer that is formed to include special hardware resources and a configuration that facilitates using the micro-sequencer as a real-time baseband controller. The microsequencer includes a 72-bit correlator that way also be used as an accumulator. The correlator is able to communicate with a 72-bit arithmetic logic unit, enabling the correlator to act as an accumulator, as well as a plurality of clocks and timers that facilitate the timing functionality to satisfy Bluetooth specifications. More specifically, the microsequencer includes at least four clocks and eight times. The four clocks include an externally driven Bluetooth clock, an externally driven real-time clock, a native Bluetooth clock and a native real-time clock. The microsequencer further includes at least four registers for temporarily storing computational data. The storage registers have different sizes for storing different sized packets of computational data.
