Member Function Documentation

configure()

void tpglibs::AVXFixedPedestalSubtractProcessor::configure ( const nlohmann::json & config, const int16_t * plane_numbers )

overridevirtual

Configure the number of startup samples to use before fixing.

Parameters

config	JSON config for start period per plane.
plane_numbers	Array of plane numbers. Gives the channels to apply the start period.

Implements tpglibs::AbstractProcessor< __m256i >.
