PSoC 5, 3 & 1 MCU

        Hi all, I am attempting to utilize the arm dsp cores. I have found examples at http://www.disca.upv.es/aperles/arm_cortex_m3/curset/CMSIS/Documentation/DSP/html/arm_fft_bin_exampl... primarily the fft example is what I am interested in replicating, but I am confused slightly on how cores work. I have used the picoblaze core on Xilinx Spartan-6 before but I have never used premade cores, especially for psoc. I have looked at the psoc system reference guide and found information on CMSIS under startup and linking, but it does not make full sense to me. could someone please point me in the right direction to get me started? also will I have to download all the files individually that I need such as the arm_math.c for the fft example (if so I think that's the only file I need?), or will I just need to download the CMSIS version 4.3 from arms website https://silver.arm.com/browse/CMSIS# I'm trying to implement spectral flux analysis and autocorrelation using these cores and I think they are a good place to start. Thanks in advance, Scarlson
