1. A signal processing device for configuring one or more scalar or vector processors according to a switching pattern, the signal processing device comprising: one or more vector processors configured to perform vector processing of a signal using a parameter, the signal being representative of a radio signal received from an antenna; one or more scalar processors configured to perform scalar processing for generating the parameter; a first routing circuit comprising a first plurality of switches, the first routing circuit being coupled to the one or more vector processors and the one or more scalar processors, and being configured to transfer the parameter from the one or more scalar processors to the one or more vector processors; a second routing circuit comprising a second plurality of switches, the second routing circuit being coupled to the one or more vector processors and another circuit that is configured to input the signal to the second routing circuit, and being configured to transfer the signal among the one or more vector processors and the other circuit; and a control processor configured to output a switching control signal, based on a type of process to be performed on the signal and a correspondence table, to the first plurality of switches of the first routing circuit and the second plurality of switches of the second routing circuit, according to a switching pattern table including information on a plurality of processors including the vector processors and the scalar processors, and the correspondence table associated with the plurality of processors for the type of process to be performed on the signal, wherein the first plurality of switches of the first routing circuit and the second plurality of switches of the second routing circuit are respectively switched, based on the switching control signal, so as to selectively turn on or off the one or more vector processors and the one or more scalar processors for performing the type of process on the signal, based on the switching control signal that is configured to specify the switching pattern based on the type of process including one of: a cell search process, a random access channel (RACH) process, and a shared channel (SCH) transmission/reception process.
