OMAPL137-HT: Performance Benchmarks

Part Number: OMAPL137-HT
Other Parts Discussed in Thread: OMAPL138

I am trying to find out performance benchmarks for this dsp. Specifically I am looking for 1024 point Complex FFT (Radix 4, with reversal) Speed (in milliseconds) and required Cycles. 

Thank you

    Please checkout the DSP core benchmarks for this device provided here:
    www.ti.com/.../core-benchmarks.page

    Please refer to the notes to see how these benchmarks were captured. The single precision complex FFT function is part of our standard DSPLIB. Note OMAPL137 and OMAPL138 share the same memory architecture, and DSP core so you can replicate these numbers on your device as is. The time is compute for 456 Mhz DSP so you will need to linear scale based on your device frequency.

    Hope this helps.
