Hi
I'm looking for an example of FFT adaptive scaling in the SPT (R274) ?
I have searched through SW32R37-RSDK-RTM-1.0.0 release and there seems to be no examples included.
The UI in the S32 DS does not seem to generate code that will assemble without errors.
This code works for non-adaptive FFT.
win .caddr .real .cmplx_win .shift4 0x200 0x8000, 0x8800, WIN_ADDR_1024_UNIF, 4, 1, .mod0, 2
rdx4 .real .no_win .no_repeat .qext .noovs .round0 .shift8 0x200 0x8800, 0x9000, 1, 1, TWI_ADDR_512_UNIF, 0
rdx4 .cmplx .no_win .no_repeat .qext .noovs .round1 .nosft 0x200 0x9000, 0x8800, 1, 1, TWI_ADDR_512_UNIF, 0
rdx4 .cmplx .no_win .no_repeat .qext .noovs .round2 .nosft 0x200 0x8800, 0x9000, 1, 1, TWI_ADDR_512_UNIF, 0
rdx4 .cmplx .no_win .no_repeat .qext .noovs .round3 .nosft 0x200 0x9000, 0x8800, 1, 1, TWI_ADDR_512_UNIF, 0
rdx2 .cmplx .no_repeat .qext .noovs .round4 .nosft .nosplit 0x200 0x8800, 0x8C00, TWI_ADDR_512_UNIF,1, 1
My best guess at adaptive as generated by the S32 Design Studio (will not assemble)
Errors are all the same - No version of the instruction rdx4 matches ........
