Greetings DSP Guru's
Does anyone have experience with the Xilinx MAC FIR V3.0
I am interested in implementing a polyphase decimator. The Xilinx data sheet is lacking in the timing department for the polyphase decimator. A simple simulation test seems to fail Input a impulse -> output should equal the FIR coeffs. The decimation is 4 and this is where the impulse is (@ sample 4)
The MAC FIR core works under this test without decimation.
Any insight would be appreciated.
