Early Out Filter Accelerator Systems and Methods

Filter circuitry configured to:

• model at least a portion of a digital filter;
• determine a multiplication factor based on respective filter coefficients of filter components of the digital filter;
• determine an addition offset based on the respective filter coefficients;
• receive an input signal;
• combine the multiplication factor, the addition offset, and the input signal to generate a filtered signal, wherein the filtered signal is equivalent to processing the input signal through the digital filter;
• and
• output the filtered signal.

A non-transitory, machine-readable medium comprising instructions, wherein, when executed by one or more processors, the instructions cause the one or more processors to control operations of filter circuitry or to perform the operations, the operations comprising:

• modeling at least a portion of a digital filter;
• determining a multiplication factor based on respective filter coefficients of filter components of the digital filter;
• determining an addition offset based on the respective filter coefficients;
• receiving an input signal;
• multiplying the input signal by the multiplication factor to generate a multiplied signal;
• adding the addition offset to the multiplied signal to generate a filtered signal, wherein the filtered signal is equivalent to processing the input signal through the digital filter;
• and
• outputting the filtered signal.
