Architectural design issues for digital cellular products

This paper is a case study of the design of a digital cellular radio. Working through its design to solve some of the architectural design issues of the portable digital cellular radio reveals some interesting tradeoffs and benefits of using highly integrated microcontrollers in digital cellular communication products. The key points to consider are the maximum frequency required to accomplish system events and the response time of the microcontroller memories and peripherals. Digital cellular radios manage their average power consumption in three ways: by allocating resources on demand, by disabling sections not in use, and by dynamically changing the operating frequency of the baseband processor to efficiently meet battery life goals
