ADSP-SC58x FFTA module is designed for high performance pipe-lined FFT/IFFT operations. The following tables provides the FFTA benchmark numbers measured on the bench with ADSP-SC589 EZ-Kit.
|No. of Points||CFFT Performance in CCLK ccyles||CFFT Performance in us||IFFT Performance in CCLK ccyles||IFFT Performance in us|
- The numbers were measured with the ADSP-SC5xx_EZ-KIT BSP example code SmallFFTDescriptorChain available at the path: \ADSP-SC5xx_EZ-KIT\Examples\drivers\fft.
- The code was run for multiple channels (10 channels for 64,128,256,512 points, 4 channels for 1024 points, and 2 channels for 2048 points) and multiple iterations(100). The cycles mentioned are the average core cycles taken per channel per iteration.
