◆ DSPLIB_svd_small_init_ci()

template<typename dataType >
DSPLIB_STATUS DSPLIB_svd_small_init_ci ( DSPLIB_kernelHandle  handle,
const DSPLIB_bufParams2D_t bufParamsIn,
const DSPLIB_bufParams2D_t bufParamsU,
const DSPLIB_bufParams2D_t bufParamsV,
const DSPLIB_bufParams1D_t bufParamsDiag,
const DSPLIB_bufParams1D_t bufParamsSuperDiag,
const DSPLIB_svd_small_InitArgs pKerInitArgs 
)

This function is the initialization function for the C7x implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_svd_small_init.

This function determines the configuration for the streaming engine resources based on the function call parameters, and the configuration is saved in bufPBlock array. In the kernel call sequence, DSPLIB_svd_small_exec_ci would be called later independently by the application. When DSPLIB_svd_small_exec_ci runs, it merely retrieves the configuration from the bufPBlock and uses it to set up the hardware resources. This arrangement is so that DSPLIB_svd_small_exec_ci does not lose cycles to determine the hardware configuration.

Parameters
[in]handle: Active handle to the kernel
[in]bufParamsIn: Pointer to the structure containing dimensional information of input buffer
[out]bufParamsU: Pointer to the structure containing dimensional information of output buffer U
[out]bufParamsV: Pointer to the structure containing dimensional information of output buffer V
[out]bufParamsDiag: Pointer to the structure containing dimensional information of output buffer Diag
[out]bufParamsSuperDiag: Pointer to the structure containing dimensional information of output buffer SuperDiag
[in]pKerInitArgs: Pointer to the structure holding init parameters
Returns
Status value indicating success or failure. Refer to DSPLIB_STATUS.

DSPLIB_STATUS DSPLIB_svd_small_exec_ci ( DSPLIB_kernelHandle  handle,
void *restrict  pA,
void *restrict  pU,
void *restrict  pV,
void *restrict  pDiag,
void *restrict  pSuperDiag,
void *restrict  pU1 
)

This function is the main execution function for the C7x implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_svd_small_exec.

Parameters
[in]handle: Active handle to the kernel
[in]pA: Pointer to the input buffer pA
[out]pU: Pointer to the output buffer pU
[out]pV: Pointer to the output buffer pV
[out]pDiag: Pointer to the output buffer pDiag
[out]pSuperDiag: Pointer to the output buffer pSuperDiag
[in]pU1: Pointer to the buffer pU1
Returns
Status value indicating success or failure. Refer to DSPLIB_STATUS.
Performance Considerations:
For best performance,
  • the input and output data buffers are expected to be in L2 memory.
  • the buffer pointers are assumed to be 64-byte aligned
Assumptions:
The arrays A, U, V, Diag, SuperDiag, U1, V1 and Scratch are stored in distinct arrays In-place processing of A is not allowed.
