auto aie::cos | ( | const Vec & | v | ) | ->aie_dm_resource_remove_t |
Performs a cosine operation on all elements in the input vector. The input vector can either be of float values in radians or integers. The floating-point range is [-Pi, Pi]. Integer values are handled as a fixed-point input value in Q1.31 format scaled with 1/Pi (input value 2^31 corresponds to Pi). In this case only the upper 20-bit of the input value are used.
According to input type, returns a vector of float or of signed Q.15 fixed-point format.
v | Input vector. The type must meetRealVector. |
auto aie::cos | ( | E | a | ) |
Performs a cosine operation on a single value. The input can either be a float value in radians or an integer. The floating-point range is [-Pi, Pi]. Integer values are handled as a fixed-point input value in Q1.31 format scaled with 1/Pi (input value 2^31 corresponds to Pi). In this case only the upper 20-bit of the input value are used.
According to input type, the returned value is either a float or a signed Q.15 fixed-point format.
a | Value. The type must meetRealElem. |
auto aie::sin | ( | const Vec & | v | ) | ->aie_dm_resource_remove_t |
Performs a sine operation on all elements in the input vector. The input vector can either be of float values in radians or integers. The floating-point range is [-Pi, Pi]. Integer values are handled as a fixed-point input value in Q1.31 format scaled with 1/Pi (input value 2^31 corresponds to Pi). In this case only the upper 20-bit of the input value are used.
According to input type, returns a vector of float or of signed Q.15 fixed-point format.
v | Input vector. The type must meetRealVector. |
auto aie::sin | ( | E | a | ) |
Performs a sine operation on a single value. The input can either be a float value in radians or an integer. The floating-point range is [-Pi, Pi]. Integer values are handled as a fixed-point input value in Q1.31 format scaled with 1/Pi (input value 2^31 corresponds to Pi). In this case only the upper 20-bit of the input value are used.
a | Value. The type must meetRealElem. |
auto aie::sincos | ( | const Vec & | v | ) | -> std::pair<aie_dm_resource_remove_t |
Same as sin and cos, but performs both operations and returns a std::pair of vectors of result values. The first vector contains the sine values, the second contains the cosine values
According to input type, returns a pair of vectors of float or of signed Q.15 fixed-point format.
v | Input vector. The type must meetRealVector. |
auto aie::sincos | ( | E | a | ) |
Performs both sin and cos, and returns both values as an std::pair (sin first, then cos). The input can either be a float value in radians or an integer. The floating-point range is [-Pi, Pi]. Integer values are handled as a fixed-point input value in Q1.31 format scaled with 1/Pi (input value 2^31 corresponds to Pi). In this case only the upper 20-bit of the input value are used.
According to input type, the returned values are either float or signed Q.15 fixed-point format.
a | Value. The type must meetRealElem. |
auto aie::sincos_complex | ( | const Vec & | v | ) | ->vector |
Same as sincos, but returns both values as the real and imaginary parts in a vector of complex values (cos in the real part, sin in the imaginary).
According to input type, returns a vector of float or of signed Q.15 fixed-point format.
v | Input vector. The type must meetRealVector. |
auto aie::sincos_complex | ( | E | a | ) | -> std::conditional_t |
Same as sincos, but returns both values as the real and imaginary parts of a complex number (cos in the real part, sin in the imaginary part).
Each part of the returned complex number is either a float or a signed Q.15 fixed-point format.
a | Value. The type must meetRealElem. |
