Finite impulse response (FIR) filter compiler

A method of compiling a filter, comprising:

• providing a first set of filter coefficients;
• determining an expected filter spectral response based in part upon the first set of filter coefficients;
• comparing a desired filter spectral response to the expected filter spectral response;
• determining that the expected filter spectral response is substantially the same as the desired filter spectral response;
• estimating an implementation cost of the filter using the first set of filter coefficients;
• determining whether the implementation cost is acceptable, and if it is determined that the implementation cost is unacceptable, updating the design of the filter;
• generating a filter implementation output file operable to implement the filter on a device.

A computer system, comprising:

• means for providing a first set of filter coefficients;
• means for determining an expected filter spectral response based in part upon the first set of filter coefficients;
• means for comparing a desired filter spectral response to the expected filter spectral response;
• means for determining that the expected filter spectral response is substantially the same as the desired filter spectral response;
• means for estimating an implementation cost of the filter using the first set of filter coefficients;
