Project Abstract for ECE734 Spring ‘02 Erick L. Oberstar Investigation of the implementation of a 2nd order fixed point IIR filter on the Atmel AVR line of microcontrollers. Investigation of algorithm implementation on the AT90S8535 (without hardware multiplier) and implementation on the ATMega163 (with hardware multiplier). Analyze and discuss the CodevisionAVR compilers implementation of fixed-point multiplication pertaining to the IIR filter implementation. Propose, test, and discuss methods to optimize the filter implementation on both target processors.
