  • HERCULES-DSPLIB: Bug in arm_min_q15() and arm_min_q7() functions

    TI Thinks Resolved
    Part Number: HERCULES-DSPLIB Hi, I tried to report this bug via TI customer support, but they redirected me to the e2e forum. So, the case is: During our internal tests it was found that two HERCULES-DSPLIB (Cortex-R4 CMSIS DSP Lib) functions show buggy…

  • HERCULES-DSPLIB: FFT calculation using Hercules DSP LIB

    TI Thinks Resolved
    Part Number: HERCULES-DSPLIB I've been using arm_rfft_f32 to perform FFT on a sequence of real samples from an ADC. The signal is a 50 Hz signal and I am performing FFT every 200ms on a set of 2048 samples. The frequency spectrum is distributed in…

  • HERCULES-DSPLIB: FFT of real valued data in time domain

    Resolved
    Part Number: HERCULES-DSPLIB Other Parts Discussed in Thread: AM6546 We are using the Hercules DSPLIB v1.0.0 to perform some signal processing in our application. To simply touch base with the Library we simply tried to perform an 128-point FFT of a DC…

  • RE: TMS570LS3134: Delfino vs Hercules as a safety co-processor. Serial firmware update of the device.

    The DSP library can be used for FFT calculation. But the Hercules devices do not have a built-in FFT hardware which can process the jobs in parallel and can achieve order-of-magnitude throughput improvements over software FFTs. https://www.ti.com/tool…

  • HERCULES-DSPLIB: TMS570 safety manual/support package

    TI Thinks Resolved
    Part Number: HERCULES-DSPLIB Hi team, A customer had asked if we had a safety manual/support package for the DSPLib (HERCULES-DSPLIB) portion? They have the Hercules DiagLib (SAFETI_DIAG_LIB) but looking for a companion type of package for the DSPLib…
