The numerical calculation with improved precise coordinate revolution (CORDIC) the processor

摘要

The CORDIC angular computer for the baseband IC receiver (36), input scaling expedient (38) and also, the CORDIC algorithm calculation processor (37) it has. Input scaling expedient receives the input data, scaling does that input data, gives that to the CORDIC processor. Output scaling expedient (62), the output data is received from the CORDIC processor, that output data re-scaling is done, the angle which was calculated is given. With typical execution form, as for input scaling expedient, it shifts the input data for signal compression, it has the expedient which gives the shift signal which corresponds to the shift of the input data as for output scaling responds to the shift signal.
