Low Power FIR Filter: Overview Details Name: lowpowerfir Created: 28-Mar-2003 00:02:09 Updated: 29-Oct-2006 02:26:56 CVS: no files in cvs Other project properties Category :: DSP core Development status :: Production/Stable Project maintainers Mike Livesley Jason Meredith Statistics view Opened bugs project has opened bugs Description This project was undertaken to produce a low power FIR filter for inclusion in a VHDL target library. The design was completed using OrCAD's Capture CIS, from this the VHDL code has been extracted. This method has allowed complete testing of the system. The power consumption of various arithmetic architectures has been investigated, and the results have been provided in the intial report (FIRLowPowerConsiderations.doc). These results have enabled the correct power/performance optimization for the FIR filter design. The design was produced at the gate level, enabling low-power architecture to be implemented using the extracted VHDL netlists. Each part of the design is explained within the design report (FIRLowPowerFinalReport.doc), along with the techniques for the operation of the system. Features Simple operation Programmable with up to 15 taps Operates at sample frequency Low power design, low control logic overhead Power considerations and design reports available Status Filter complete and fully tested, VHDL source and testbenches available Low-power analysis report available FIR filter design report available
