Data allocating apparatus, signal processing apparatus, and data allocating method

摘要

A data allocating apparatus, a signal processing apparatus, and a data allocating method thereof are provided. A plurality of storage units sequentially arranged is provided. A control unit of the data allocating apparatus determines whether the single period output data has the longest storing time in Real-valued Fast Fourier transform (RFFT) output data according to a lifetime analysis, wherein the storing time is a time that the RFFT output data is stored in storage units. The single period output data having the longest storing time is inputted into first storage units of the storage units, and the single period output data not having the longest storing time is inputted into second storage units of the storage units by the control unit. The first storage units are arranged at the last of the storage units, and the second storage units are arranged in front of the first storage units.

1. A data allocating method, adapted to a signal processing apparatus, the data allocating method comprising:
providing a plurality of sequentially arranged storage units; obtaining a plurality of single period output data in a plurality of real-valued fast Fourier transform (RFFT) output data; determining whether the single period output data has the longest storing time in the RFFT output data according to a lifetime analysis, wherein the storing time is a time that the RFFT output data is stored in the storage units; inputting the single period output data having the longest storing time into a plurality of first storage units of the storage units, wherein the first storage units are arranged at the last of the storage units; and sequentially inputting the single period output data not having the longest storing time into a plurality of second storage units of the storage units, wherein the second storage units are arranged in front of the first storage units.
