◆ DSPLIB_blk_eswap_init_ci()

template<typename dataType >
DSPLIB_STATUS DSPLIB_blk_eswap_init_ci ( DSPLIB_kernelHandle  handle,
const DSPLIB_bufParams1D_t *  bufParamsIn,
const DSPLIB_bufParams1D_t *  bufParamsOut,
const DSPLIB_blk_eswap_InitArgs *  pKerInitArgs 
)

This function is the initialization function for the C7x implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_blk_eswap_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_blk_eswap_exec_ci would be called later independently by the application. When DSPLIB_blk_eswap_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_blk_eswap_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]bufParamsOut: Pointer to the structure containing dimensional information of ouput buffer
[in]pKerInitArgs: Pointer to the structure holding init parameters
Returns
Status value indicating success or failure. Refer to DSPLIB_STATUS.

template<typename dataType , uint32_t maskType>
DSPLIB_STATUS DSPLIB_blk_eswap_exec_ci ( DSPLIB_kernelHandle  handle,
void *restrict  pIn,
void *restrict  pOut 
)

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

The function uses one streaming engine to load the input data then endian swap operation is performed. The result is then stored using streaming address generator.

Parameters
[in]handle: Active handle to the kernel
[in]pIn: Pointer to buffer holding the input data
[out]pOut: Pointer to buffer holding the output data
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
