Abstract

In a radio transceiver having a microcomputer (11) that controls various hardware-dependent components (220) and functions (240) that form a plurality of radio control processes, a method and apparatus for executing the radio control processes includes providing the microcomputer (11) with a plurality of virtual sources (272). The virtual sources (272) are for collecting and distributing data (440) generated by the hardware-dependent components (220) and functions (240) in the radio transceiver. A plurality of hardware-independent tasks (292, 392) for executing the radio control processes are also provided by the microcomputer. A distribution controlling interface standard (228) for controlling which hardware-independent task (292, 392) will receive from which virtual source (272) is further provided by the microcomputer (11).
