  4. volk: make volk's get_machine thread safe.

    Roy Thompson authored and trondeau committed Jan 28, 2014
    Sets a local struct instead of the global while searching. When found, then sets the machine.
    
    This assumes that the pointer assignment is atomic, which it probably is on almost any platform.
  5. blocks: Add a new rotator_cc block to perform frequency shifting

    smunaut committed Jan 25, 2014
    It internally uses the rotator.h helper that was already present,
    which in turn makes uses of VOLK rotator kernel

  6. blocks/rotator: Make the input data 'const'

    smunaut committed Jan 25, 2014
    The volk kernels are const and there is no reason to clobber the input

  9. volk/rotator: Use more precise phase_inc in volk_profile

    smunaut committed Jan 28, 2014
    The kernels all expect the phase_inc to be a unity vector. Any error on
    this will compound and ultimatly make it fail

  10. volk/rotator: Fix some debug printf accessing array out-of-bound

    smunaut committed Jan 28, 2014
    Those are disabled by default, but enabling them for debugging will
    result in warnings, so might as well fix them.

  11. volk/rotator: Tighten the tolerance to 1e-3 in QA

    smunaut committed Jan 28, 2014
    It doesn't quite pass with 1e-4 yet :(

  12. volk/rotator: Fix the renormalization process (missing sqrt)

    smunaut committed Jan 28, 2014
    Note: We use _mm_sqrt_ps followed by _mm_div_ps rather than using the
          faster _mm_rsqrt_ps followed by _mm_mul_ps. It's slower but it
          avoids some numerical errors that show up clearly on spectrum
          as an image up to -80 dBc. Here the image is at -120 dBc.
    
          This is in the renormalization process anyway so the cost is
          spread on a fair amount of samples.

  13. volk/rotator: Fix the volk_32fc_s32fc_x2_rotator_32fc_generic kernel

    smunaut committed Jan 25, 2014
    abs() is an int function ...
    
    Call the right one depending on the language now.
    
    Note that I explicitely did the selection here rather than add a lv_abs()
    function in volk_complex.h because there is no GCC extension for abs() that
    would return the right type, so I'd have to stick to the cabs() function
    which would force a double cast back and forth.

  14. volk: enabling unaligned protokernels for rotator

    Added ifdefs so that the existing unaligned kernels get built and
    tested.

  1. volk: add avx u/a protokernel for 32f_x3sum_of_poly_32f

    n-west committed Jan 25, 2014
    The threshold differences have to change for volk_profile because
    of rounding errors. It was passing previously because of a bug in
    VOLK QA (bug 627) that has since been resolved.
  2. volk: fixup QA's fcompare to test all differences

    n-west committed Jan 27, 2014
    This addresses bug 627 by adding a fabs call when checking if a number
    is close to 0. If this is the case we also make sure the other buffer
    is within tolerance. For the normal test case wrap the percent difference
    in fabs rather than just the difference.
  3. volk: proposed solutions to bugs 582/583

    n-west committed Jan 23, 2014
    582 and 583 are probably compiler bugs, and an upstream bug has been filed
    on launchpad with Linaro GCC. A static cast of the tolerance is not happening
    on armhf architectures. The work around forces a cast by using the values
    immediately after assignment.
