void ckernel::log_with_base_tile(uint32_t idst, uint32_t base_scale)

Performs element-wise computation of logarithm with a specified base 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.

Return value: None

Argument Description

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

base_scale Bit representation of Inverse of log base e.g. 1/ln(2) to compute log2(x)
