A data radio has an arbitrary number of processors configured to interact with a single cryptographic engine or security module. Hardware strapping allows each card and processor to identify its location in a system. The static region of the field-programmable gate array contains the functionality to manage access to the backplane. Dynamic regions of the field-programmable gate array fabric are used to route the data correctly to and from the security module within a specific application. Software is deployed on any card with a generic load that is agnostic to its location and the hardware self-configures.

An apparatus and power saving methods are disclosed. The apparatus includes a radio communication device including at least one hardware component configured to operate in a normal mode and a power saving mode. The apparatus also includes a controller configured to monitor operations of the radio communication device and to determine whether to set the at least one hardware component to operate in the normal mode or in the power saving mode. The apparatus further includes a control mechanism associated with the at least one hardware component. The control mechanism is configured to change the operation of the at least one hardware component between the normal mode and the power saving mode based on a command received from the controller.
