#include </home/docs/checkouts/readthedocs.org/user_builds/hpm-sdk/checkouts/latest/middleware/hpm_math/hpm_math.h>

Convolution of the q15 vectors.

Parameters

[in]	*src1	points to the first input vector.

[in]	*src2	points to the second input vector.
[in]	len2	length of the second input vector.
[out]	*dst	points to the output vector where the length is len1 + len2 - 1.

Function notes: Both inputs are in 1.15 format and multiplications yield a 2.30 result. The 2.30 intermediate results are accumulated in a 64-bit accumulator in 34.30 format. The 34.30 result is then truncated to 34.15 format by discarding the low 15 bits and then saturated to 1.15 format.

inlinestatic

#include </home/docs/checkouts/readthedocs.org/user_builds/hpm-sdk/checkouts/latest/middleware/hpm_math/hpm_math.h>

Convolution of the q31 vectors.

Parameters

[in]	*src1	points to the first input vector.
[in]	len1	length of the first input vector.
[in]	*src2	points to the second input vector.
[in]	len2	length of the second input vector.
[out]	*dst	points to the output vector where the length is len1 + len2 - 1.

Function notes: Both inputs are in 1.31 format and the 64-bit accumulator has a 2.62 format and maintains full precision of the intermediate multiplication results but provides only a single guard bit. The input signals should be scaled down to avoid intermediate overflows. Scale down the inputs by log2(min(srcALen, srcBLen)), The 2.62 accumulator is right shifted by 31 bits and saturated to 1.31 forma t to yield the final result.

[in]	len2	length of the second input vector.
[out]	*dst	points to the output vector where the length is 2 * max(len1, len2) - 1.

Function notes: Both inputs are in 1.15 format and multiplications yield a 2.30 result. The 2.30 intermediate results are accumulated in a 64-bit accumulator in 34.30 format. The 34.30 result is then truncated to 34.15 format by discarding the low 15 bits and then saturated to 1.15 format.

◆ hpm_dsp_corr_q31()

static void hpm_dsp_corr_q31	(	q31_t *	src1,
		uint32_t	len1,
		q31_t *	src2,
		uint32_t	len2,

	)

inlinestatic

#include </home/docs/checkouts/readthedocs.org/user_builds/hpm-sdk/checkouts/latest/middleware/hpm_math/hpm_math.h>

Convolution of the q31 vectors.

Parameters

[in]	*src1	points to the first input vector.
[in]	len1	length of the first input vector.
[in]	*src2	points to the second input vector.
[in]	len2	length of the second input vector.
[out]	*dst	points to the output vector where the length is len1 + len2 - 1.

Function notes: Both inputs are in 1.31 format and the 64-bit accumulator has a 2.62 format and maintains full precision of the intermediate multiplication results but provides only a single guard bit. The input signals should be scaled down to avoid intermediate overflows. Scale down one of the inputs by 1/min(srcALen, srcBLen) to avoid overflows since a maximum of min(srcALen, srcBLen) number of additions is carried internally. The 2.62 accumulator is right shifted by 31 bits and saturated to 1.31 forma t to yield the final result.

[in]	len2	length of the second input vector.
[out]	*dst	points to the output vector where the length is 2 * max(len1, len2) - 1.

Function notes: Both inputs are in 1.7 format and multiplications yield a 2.14 result. The 2.14 intermediate results are accumulated in a 32-bit accumulator in 18.14 format. The 18.14 result is then truncated to 18.7 format by discarding the low 7 bits and then saturated to 1.7 format.
