nrf_axon_exp_11p12()

nrf_axon_result_e nrf_axon_exp_11p12	(	const int32_t *	in_ptr,
		int32_t *	out_ptr,
		uint16_t	length,
		nrf_axon_syncmode_blocking_e	block_mode,
		bool	keep_reservation )

"exp"=> "exponent" (e to the x) Calculates the exponent of vector input, output=exp(input). Input and output are both interpreted as q11.12. If the input radix isn't 11.12, there is no analogous way to logn() to correct the output. (ie, one can't add or multiple by an offset to correct the result). The effective input range (without saturation) is -8.3 to 7.46

Parameters

input	pointer to the input, q11.12 sign-extended to 32bits.
input_length	length of the input (in elements). Must be a multiple of 2, at least 2, and maximum of 512.
output	pointer to the output, q11.12 sign-extended to 32bits. Output can overlap/overwrite input.
cmd_buf_info_ptr	compiled axon code is appended into this structure.

Returns

kAxonResultSuccess on success or a negative error code (see nrf_axon_result_e)
