arg()

template<typename T>

T pulp::signal::rt::arg ( const std::complex< T > & z )

inlinenoexcept

Counted std::arg (an atan2). Bit-identical result.

cos()

template<typename T>

T pulp::signal::rt::cos ( T x )

inlinenoexcept

Counted std::cos. Bit-identical result.

count_bins()

void pulp::signal::rt::count_bins ( std::uint64_t n )

inlinenoexcept

Record n units of per-bin accumulation work.

count_fft()

void pulp::signal::rt::count_fft ( )

inlinenoexcept

Record one FFT execution.

count_trig()

void pulp::signal::rt::count_trig ( std::uint64_t n = 1 )

inlinenoexcept

Record n transcendental evaluations.

exp()

template<typename T>

T pulp::signal::rt::exp ( T x )

inlinenoexcept

Counted std::exp. Bit-identical result.

polar()

template<typename T>

std::complex< T > pulp::signal::rt::polar ( T magnitude, T phase )

inlinenoexcept

Counted std::polar. Bit-identical result.

sin()

template<typename T>

T pulp::signal::rt::sin ( T x )

inlinenoexcept

Counted std::sin. Bit-identical result.

work_counts()

RtWorkCounts pulp::signal::rt::work_counts ( )

inlinenoexcept

Current process-wide totals.

Take one before and one after the work of interest and subtract.

Variable Documentation

kWorkCountersEnabled

bool pulp::signal::rt::kWorkCountersEnabled = 0 != 0

inlineconstexpr

True when this build counts operations.

A gate that reads counts must check this first: with counting compiled out every delta is zero, which would read as "no work" rather than "not measured".
