DSPLIB_STATUS DSPLIB_qrd_solver_init_ci ( DSPLIB_kernelHandle  handle,

This function is the initialization function for the C7x implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_qrd_solver_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_qrd_solver_exec_ci would be called later independently by the application. When DSPLIB_qrd_solver_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_qrd_solver_exec_ci does not lose cycles to determine the hardware configuration.

Parameters
[in]handle: Active handle to the kernel
[in]bufParamsQ: Pointer to the structure containing dimensional information of Q matrix
[in]bufParamsR: Pointer to the structure containing dimensional information of R matrix
[in]bufParamsB: Pointer to the structure containing dimensional information of input vector B
[in]bufParamsY: Pointer to the structure containing dimensional information of temporary vector Y
[out]bufParamsX: Pointer to the structure containing dimensional information of ouput vector X
[in]pKerInitArgs: Pointer to the structure holding init parameters
Returns
Status value indicating success or failure. Refer to DSPLIB_STATUS.

)

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

The function implements optimized version for DSPLIB_qrd_solver_exec.

Parameters
[in]handle: Active handle to the kernel.
[in]pQ: Pointer to the input matrix Q.
[in]pR: Pointer to the input matrix R.
[in]pB: Pointer to the input vector B.
[in]pY: Pointer to the temporary vector Y.
[out]pX: Pointer to the output vector X.
[in]pD: Pointer to the Scratch buffer D.
[in]pR1: Pointer to the Scratch buffer for transposed matrix of R.
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
