Serial IIR filter structure generator for ASICs
Marián Pristach, Lukáš Fujčík · Digital Library (University of West Bohemia) · 2012
The paper presents generator of an infinite impulse response (IIR) digital filter structure for implementation in application specific integration circuits (ASICs). The paper describes the filter architecture with serial calculation. The serial architecture utilizes one shared multiply and accumulate (MAC) unit in order to achieve minimal area on chip. Software in C++ language was written for automatic filter generation. The software generates fully synthesizable VHDL description of filter, batch file for simulator and test-bench file for automatic filter verification from the filter specification file.
