Title:
DFT計算用装置
Document Type and Number:
Japanese Patent JP5269911
Kind Code:
B2
Abstract:
A device to perform DFT calculations, for example in a GNSS receiver, including two banks of multipliers by constant integer value, the values representing real and imaginary part of twiddle factors in the DFT. A control unit selectively routes the data through the appropriate multipliers to obtain the desired DFT terms. Unused multipliers are tied to constant input values, in order to minimize dynamic power.
