template class xf::hpc::rtm::Domain3D¶

#include "domain3d.hpp"

Overview¶

Domain3D class used to partition the pressure field to maximize the kernel performance.

Parameters:

t_HalfOrder	the half spatial discretization order
t_MaxDimZ	the maximum dim along z-axis the kernel can process
t_MaxDimY	the maximum dim along y-axis the kernel can process
t_PEZ	the number of processing elements along z-axis
t_PEX	the number of processing elements along x-axis
t_NumSM	the number of streaming modules in the kernel

Methods¶

mem2stream¶

template <typename t_InterfaceType>
void mem2stream (
    const t_InterfaceType* p_mem,
    hls::stream <t_InterfaceType>& p_str
    ) const

mem2stream reads data memory to a stream

Parameters:

t_InterfaceType	the datatype in memory
p_mem	the first memory port
p_str	the output stream

stream2mem¶

template <typename t_InterfaceType>
void stream2mem (
    hls::stream <t_InterfaceType>& p_str,
    t_InterfaceType* p_mem
    ) const

stream2mem reads write alternatively to two memory addresses from a stream

Parameters:

t_InterfaceType	the datatype in memory
p_mem	the first memory port
p_str	the input stream

memSelStream¶

template <typename t_InterfaceType>
void memSelStream (
    const bool p_sel,
    const t_InterfaceType* p_mem0,
    const t_InterfaceType* p_mem1,
    hls::stream <t_InterfaceType>& p_str
    ) const

mem2stream reads data memory to a stream

Parameters:

t_InterfaceType	the datatype in memory
p_sel	the signal to select read port
p_mem0	the first memory port
p_mem1	the second memory port
p_str	the output stream

streamSelMem¶

template <typename t_InterfaceType>
void streamSelMem (
    const bool p_sel,
    hls::stream <t_InterfaceType>& p_str,
    t_InterfaceType* p_mem0,
    t_InterfaceType* p_mem1
    ) const

stream2mem reads write alternatively to two memory addresses from a stream

Parameters:

t_InterfaceType	the datatype in memory *
p_sel	the signal to select read port
p_mem0	the first memory port
p_mem1	the second memory port
p_str	the input stream
