Abstract
An extremely compact, full featured portable radio architecture conserves power by allowing a processor to sleep except when it needs to perform tasks. A lower power processor which acts principally as an interrupt controller but which performs other functions as well (e.g., tone decode, synthesizer lock monitoring, etc.) so the main processor can sleep as much as possible and yet is assured of being awoken promptly when its processing power is required. The resulting portable radio has extremely low power consumption (e.g., on the order of 75 milliamperes during trunked mode operation)--thereby permitting even a relatively small battery pack to provide nearly 8 hours of continuous operation. The portable radio with battery is small and lightweight enough to fit into a front shirt pocket.
