A transceiver-processor building block (700) for implementation of radio
systems, an example being used in an electronic radio system multifunction slice,
includes several transceivers (704-710), a processor connected to the transceivers
(702), and a local RF control bus (726) coupled between the processor
(702) and the transceivers (704-710). A radio network bus (716)
is also provided and connected to the processor (702). The local RF control
bus (726) is inaccessible directly from outside the multifunction slice.
In contrast, the radio network bus (716) is accessible directly from outside
the multifunction slice to allow "stacking" of multiple slices. The building block
(700) may also include an external control bus (728) connected to
the processor (702). An external control bus connector (730) then
provides direct accessibility to the external control bus (728) from outside
the multifunction slice.
