Logicore Peak Cancellation CFR (PC-CFR) v2.0 - Is the reconfigurable coefficients variant of the PC-CFR is affected by the s6 bram issue?


Is the reconfigurable coefficients variant of the PC-CFR affected by the Spartan-6 FPGA BRAM issue (Xilinx Answer 34533)?


The PC-CFR is affected by by the S6 BRAM issue (Xilinx Answer 34533) In order to work round any BRAM issues the advice is that the cpulse coefficients are padded with a zero at each end, and that address zero is not written to. This does reduces the effective number of coeffs supported by 2 but this will not affect the cores ability to perform its task. The number of taps will need to be set the the full width of the zero-padded cpulse.
