CoefficientSource - Specify source for FIR or IIR filter coefficients

Settings

'Internal' (default)

Coefficients are obtained from the filter object and hard coded.

ProcessorInterface

Generate a memory interface, which can be driven by an external microprocessor, for coefficients.

When you specify 'ProcessorInterface', the generated entity or module definition for the filter includes the following port definitions:

• coeffs_in: Input port for coefficient data

• write_address: Write address for coefficient memory

• write_enable: Write enable signal for coefficient memory

• write_done: Signal to indicate completion of coefficient write operation
