Configurable MAC Pipelines for Reconfigurable FIR Filter Taps

The patent implements dynamic reconfiguration of the FIR filter by allowing the number of taps and multiplier-accumulator circuits to be changed during operation. Configuration registers store programmable parameters that can be modified in-situ, enabling the filter to adapt to different processing requirements without physical reconfiguration. This dynamic approach resolves the contradiction by making the device adaptable while maintaining manageable complexity through systematic design.

The patent changes key parameters of the FIR filter (number of taps, number of multiplier-accumulator circuits) from fixed to programmable values. Configuration registers hold these parameters and allow them to be modified during operation. By enabling parameter changes, the system achieves adaptability while the structured parameter management keeps device complexity controlled.

The patent creates a universal FIR filter architecture that can perform multiple filtering functions by changing its configuration parameters. The same hardware structure with programmable taps and multiplier-accumulator circuits can be reconfigured for different filter types and applications. This multi-functionality approach improves adaptability while avoiding the need for multiple separate fixed filters, thereby controlling overall device complexity.

The patent segments the FIR filter into configurable modules including programmable taps and separate multiplier-accumulator circuits. This modular segmentation allows independent configuration of each component through configuration registers, enabling adaptability while managing complexity through systematic organization of filter elements.
