Filter Design HDL Coder™

CoefficientSource - Specify source for FIR filter coefficients

Settings

'Internal' (default)

Coefficients are obtained from the filter object and hard coded.

ProcessorInterface

Generate a RAM port 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

• wr_addr: write address for the RAM

• wr_en: write enable signal for RAM

• wr_done: signal to indicate completion of coefficient write operation
