Ultra low power digital signal processing
he wide-spread and growing use of portable, battery-powered devices like cellular telephones, audio-capable personal digital assistants (PDAs), MP3 players and similar applications has resulted in an increasing demand for miniature, ultra low-power digital signal processing (DSP) technology. Many of these devices make heavy use of digital signal processing techniques like modulation, demodulati...
متن کاملDSP engine for ultra-low-power audio applications
An ultra-low-power DSP decimation/interpolation structure is described demonstrating how algorithmic and architectural schemes were employed for ultimate power efficiency in a DSP based chip set for audio applications. This circuit was designed and synthesised for a low VT 0.35 m CMOS process allowing Nyquist rate signals to be decimated from a high OSR frontend and interpolation post voice pro...
متن کاملLow-power MIMO signal processing
In this paper, we present a new adaptive error-cancellation (AEC) technique, denoted as multi-input–multi-output (MIMO)-AEC, for the design of low-power MIMO signal processing systems. The MIMO-AEC technique builds on the previously proposed AEC technique by employing an algorithm transformation denoted as MIMO decorrelating (MIMO-DECOR) transform. MIMO-DECOR reduces complexity by exploiting co...
متن کاملLow power digital signal processing
This thesis introduces a novel approach to programmable and low power platform design for audio signal processing, in particular hearing aids. The proposed programmable platform is a heterogeneous multi-processor architecture consisting of small and simple instruction set processors called mini-cores as well as standard DSP/CPU-cores that communicate using message passing. The work has been bas...
متن کاملReconfigurable processing: the solution to low-power programmable DSP
One of the most compelling issues in the design of wireless communication components is to keep power dissipation between bounds. While low-power solutions are readily achieved in an applicationspecific approach, doing so in a programmable environment is a substantially harder problem. This paper presents an approach to lowpower programmable DSP that is based on the dynamic reconfiguration of h...
