System and method for low-power digital signal processing

摘要

A system and method for low-power digital signal processing, for example, comprising adjusting a digital representation of an input signal.

主权项

1. A low-power digital processing system comprising:
at least one module that operates to, at least:
analyze an input signal represented by a first digital representation;based at least in part on the analysis of the input signal, determine whether to adjust a digital representation of a level of the input signal to a second digital representation different from the first digital representation prior to performing a next digital signal processing function on the input signal; andif it is determined to adjust the digital representation of the level of the input signal, then at least:
adjust the digital representation of a level of the input signal to the second digital representation; andperform the next digital signal processing function on the second digital representation of the input signal to form an output signal, wherein:
a level of the output signal is represented by a digital representation like the second digital representation of the level of input signal; andthe at least one module operates to adjust the digital representation of the level of the output signal to a digital representation like the first digital representation.
