This is an example project to compute FIR output with 8192 TAPS. Refer to chapter "Computing FIR Output, Tap Length Greater than 4096" in the Hardware Reference Manual for more information on this.https://www.analog.com/media/en/dsp-documentation/processor-manuals/adsp-2156x_hwr.pdf
The code also calculates the performance of FIRA along with core overhead for calculating the final output. You can understand the working of the code from the comments embedded within. Please refer to the read_me.txt for set-up related information.
