1. A software-defined radio (SDR) system configured by reconfiguration bits received from an external controller comprising: a reconfigurable baseband subsystem supporting a plurality of wireless communication standards comprising a first plurality of context-based operation reconfigurable instruction set processors CRISPs, each of said first plurality of CRISPs comprising a reconfigurable data path comprising a plurality of reconfigurable functional blocks, and a programmable finite state machine that controls said reconfigurable data path, wherein said programmable finite state machine is executing a plurality of instructions associated with a particular function; and a reconfigurable application subsystem supporting a plurality of end-user applications comprising a second plurality of CRISPs, each of said second plurality of CRISPs comprising a second reconfigurable data path comprising a plurality of second reconfigurable functional blocks, and a second programmable finite state machine that controls said second reconfigurable data path, wherein said second programmable finite state machine executing a second plurality of instructions associated with a second particular function.
