SigmaStudio and SHARC 21569 fir accelerator

Question

Hi, 
 I used the LibIntegration example project to load sigmastudio code and pass audio through SPORT 4A and 4B. i tried to add the FIR accelerator code to the project right before the sigmastudio adi_ss_schematic_process function call. but I'm getting a "Input buffer overflow detected" error. is this the right way of integrating an FIR accelerator to this project? or is there any example project where i could get a reference to how to use a fir accelerator for continuous audio playback. 
 I'm attaching both the project files, orginal project and with FIR accelerator integrated within that project.

You can get the input and output data of SigmaStudio schematic process function, so you can make use of this buffers for your FIR accelerator implementation before/after SigmaStudio schematic process. 
 ADI_SS_RESULT adi_ss_schematic_process(ADI_SS_SSN_HANDLE hSSn, int32_t num_input_samples_per_chan, adi_ss_sample_t *input_data[], adi_ss_sample_t *output_data[], ADI_SS_SSNPROPERTIES *pProperties);
