Apparatus, system and method for allocating identifiers to components of a control system

摘要

Techniques and mechanisms to enable addressing of components accessed via a control interface. In an embodiment, a plurality of identifiers is logically split into first and second pools. The first pool is available for assigning to allow addressing of components while such components are active with respect to some functionality. The second pool is available for assigning to allow addressing of components while such components are passive with respect to some functionality. In another embodiment, different respective identifiers of the first pool pool are assigned each of first one or more of the plurality of components, and a respective identifier of the second pool is assigned to each of second one or more of the plurality of components. Any two of the second one or more components that have the same address default are assigned different respective identifiers of the second pool.

1. A device comprising:
mode evaluation logic including circuitry configured to detect a first mode of a system of a radio frequency front-end and, in response, to identify:
a first set of one or more slave components coupled to a bus of the system, wherein the one or more slave components of the first set are to be active during the first mode; anda second set of one or more components coupled to the bus of the system, wherein the one or more slave components of the second set are to be passive during the first mode; assignment logic including circuitry configured to:
allocate slave identifiers of a third set of unique slave identifiers each to a respective one of an active component identifier pool and a passive component identifier pool, the third set including all slave identifiers available to be selected to configure the first mode;assign different respective slave identifiers of the active component identifier pool to each of the one or more slave components of the first set;assign a respective slave identifier of the passive component identifier pool to each of the one or more slave components of the second set, including the assignment logic to assign different respective slave identifiers to any two of the one or more slave components of the second set that have identical address defaults.
