Abstract:
1. For use in a software-defined radio processing system executing an instruction set, a reconfigurable context-based operation instruction set processor comprising: an application splitter that splits an instruction set into a control domain and a data path domain; a reconfigurable control domain, wherein the reconfigurable control domain executes at least one program using the data path domain; a reconfigurable data path configured by reconfigurable bits received from an external controller comprising a plurality of reconfigurable functional blocks to carry out instructions of data path domain; a programmable finite state machine configured by reconfigurable bit received from the external controller, wherein each state of said programmable finite state machine is associated with a first context controlling said reconfigurable data path, wherein said instruction set comprises a plurality of subsets, each subset associated with a specific context, wherein at least one subset includes a plurality of instructions, wherein said programmable finite state machine executing a first one of said plurality of subsets, said first subset associated with said first context; and a power management controller deactivating a part of said reconfigurable context-based operation instruction set processor by 1) said external controller when the control domain is inactive or 2) a time period a second reconfigurable context-based operation instruction set processor of executing a second context of said plurality of subsets when a second control domain is active.
