INTEGRATED CONTROL AND SIGNAL PROCESSING IN A CELLULAR TELEPHONE ABSTRACT OF THE DISCLOSURE Control functions are integrated into the digital signal processing (DSP) chip functioning as the central processor unit (CPU) for the subscriber's cellular telephone unit, eliminating the microcontroller and other support chips. The integration provided is not a physical integration combining the DSP and microcontroller chips into a single chip architecture, but rather a logical (i.e., software) integration. A real time pre?mptive executive controls the execution of the different functions and the messaging between them. The amount of code that has to run on the DSP chip acting as the CPU is larger than the address space of the DSP chip, so the code memory is divided into banks with only one bank being activated at a time. It is the job of the real time executive to activate the banks as required to control the various functions.
