Functions
-
void
riscv_q7_to_q15_no_shift(const q7_t *pSrc, q15_t *pDst, uint32_t blockSize) Converts the elements of the Q7 vector to Q15 vector without left-shift.
Converts the elements of the q7 vector to q15 vector without left-shift.
The equation used for the conversion process is:
- Return
none.
- Description:
- Parameters
[in] *pSrc: points to the Q7 input vector[out] *pDst: points to the Q15 output vector[in] blockSize: length of the input vector
-
void
riscv_q7_to_q15_reordered_no_shift(const q7_t *pSrc, q15_t *pDst, uint32_t blockSize) Converts the elements of the Q7 vector to reordered Q15 vector without left-shift.
Converts the elements of the q7 vector to reordered q15 vector without left-shift.
This function does the q7 to q15 expansion with re-ordering
- Return
none.
- Parameters
[in] *pSrc: points to the Q7 input vector[out] *pDst: points to the Q15 output vector[in] blockSize: length of the input vector
is converted into:
This looks strange but is natural considering how sign-extension is done at assembly level.
The expansion of other other oprand will follow the same rule so that the end results are the same.
The tail (i.e., last (N % 4) elements) will still be in original order.

void
riscv_q7_to_q15_with_offset(const q7_t *src, q15_t *dst, uint32_t block_size, q7_t offset) Converts the elements from a q7 vector to a q15 vector with an added offset.
The equation used for the conversion process is:
- Return
none.
- Description:
- Parameters
[in] *src: points to the q7 input vector[out] *dst: points to the q15 output vector[in] block_size: length of the input vector[in] offset: q7 offset to be added to each input vector element.
-
void
riscv_q7_to_q7_no_shift(const q7_t *pSrc, q7_t *pDst, uint32_t blockSize) Converts the elements of the Q7 vector to Q7 vector without left-shift.

- Return
none.
- Description:
- Parameters
[in] *pSrc: points to the Q7 input vector[out] *pDst: points to the Q7 output vector[in] blockSize: length of the input vector
