create_duplicated_lut - 2025.2 English

template <typename T>
std::vector <T> create_duplicated_lut (
    const T* lut,
    size_t lut_size
    ) const

Creates a duplicated LUT by replicating entries based on duplicateLutEntry.

This function creates a duplicated lookup table where entries are replicated to meet the parallel access requirements of AIE-ML and AIE-MLv2 devices. For devices that support parallel access of 4 (int16 and bfloat16 on AIE-ML), every group of lutValsInLUTentry values is duplicated duplicateLutEntry times to enable efficient parallel memory access.

Parameters:

T	The data type of the LUT entries (typically TT_LUT).
lut	Pointer to the original lookup table data.
lut_size	Size of the original lookup table in number of elements.

Returns:

std::vector<T> The duplicated lookup table with replicated entries.
