template class BackwardKernel¶

#include "rtm2d_kernel.hpp"

Overview¶

class BackwardKernel is used to manage and run backward kernel on FPGA

template <
    typename t_DataType,
    unsigned int t_Order,
    unsigned int t_PE
    >
class BackwardKernel: public XKernel

// typedefs

typedef WideData <t_DataType, t_PE> t_WideType
typedef WideData <t_WideType, 2> t_PairType

// fields

static const unsigned int _4k

Methods¶

loadData¶

void loadData (const string filePath)

loadData load parameters for RTM backward kernel from given path

Parameters:

filePath

the path where parameters are stored

run¶

double run (
    unsigned int p_shot,
    host_buffer_t <t_PairType>& p_snaps,
    host_buffer_t <t_DataType>& p_upb,
    host_buffer_t <t_PairType>& p_p,
    host_buffer_t <t_PairType>& p_r,
    host_buffer_t <t_DataType>& p_i
    )

run launch the RTM backward kernel with given input parameters

Parameters:

p_shot	the shot id
p_upb	the upper boundary data
p_snaps	input seismic snapshot
p_p	output seismic source wavefiled
p_r	output seismic receiver wavefiled
p_i	output seismic image

#include "rtm2d_kernel.hpp"

Overview¶

class ForwardKernel is used to manage and run forward kernel on FPGA

template <

    unsigned int t_Order,
    unsigned int t_PE
    >
class ForwardKernel: public XKernel

// typedefs
