摘要： [PROBLEMS] To provide a signal processing unit such as a software radio device capable of dynamically modifying the internal connection of function configuration during execution. [MEANS FOR SOLVING PROBLEMS] A switching module ISM1 (20) or the like selects and uses one of routing tables (60) prepared according to the signal processing and performs routing control to respective processing modules a11 or the like of the data packet. The processing module a11 or the like performs various processes by using a parameter table or the like indicating the process to be performed in accordance with the data packet. A signal processing device (1) or the like inputs a parameter packet containing an identifier such as the processing module a11 or the like and the content of the parameter table such as the processing module a11 or the like via a rewrite path from outside and transmits the parameter packet to the processing module a11 or the like specified by the identifier according to a predetermined condition, thereby dynamically rewriting the content of the parameter table.
