Please refer to documentation for any_init.

template<bool fast_and_approx = false, bool is_fp32_dest_acc_en = DST_ACCUM_MODE>
void ckernel::log_tile(uint32_t idst)

Performs element-wise computation of logarithm on each element of a tile in DST register at index tile_index. The DST register buffer must be in acquired state via acquire_dst call. This call is blocking and is only available on the compute engine.

Note: The base scale is the bit representation of the inverse of the log base. e.g. 1/ln(2) for log2(x) is 0x3fb8aa3b.

Return value: None

Argument Description

idst The index of the tile in DST register buffer to perform the computation on
