echo cancellation

We’re currently using the Cirrus CS48LV12 (DSP) and CS42L73 (Codec). It appears that Cirrus isn’t interested in supporting the DSP/echo cancellation code, so I’m looking for an alternative. One option would be to purchase the code and run it on the NXP K65 that’s in the design, but we’re short on MIPs, so I either need to find a higher performance CPU or add a DSP/M4? to run the DSP code. Since we’re changing the DSP, I suspect I should also look at changing the CODEC to something simpler/lower cost. Any suggestions would be greatly appreciated.
