Function Documentation

◆ DSPLIB_matMul_init_ci()

template<typename dataType >
DSPLIB_STATUS DSPLIB_matMul_init_ci ( DSPLIB_kernelHandle  handle,
const DSPLIB_bufParams2D_t bufParamsIn0,
const DSPLIB_bufParams2D_t bufParamsIn1,
const DSPLIB_bufParams2D_t bufParamsOut,
const DSPLIB_matMul_InitArgs pKerInitArgs 
)

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

This function determines the configuration for the streaming engine and MMA hardware resources based on the function call parameters, and the configuration is saved in bufPBlock array. In the kernel call sequence, DSPLIB_matMul_exec_ci would be called later independently by the application. When DSPLIB_matMul_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_matMul_exec_ci does not lose cycles to determine the hardware configuration.

Parameters
[in]handle: Active handle to the kernel
[in]bufParamsIn1: Pointer to the structure containing dimensional information of input buffer 1
[in]bufParamsIn2: Pointer to the structure containing dimensional information of input buffer 2
[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.

◆ DSPLIB_matMul_exec_ci()

template<typename dataType >
DSPLIB_STATUS DSPLIB_matMul_exec_ci ( DSPLIB_kernelHandle  handle,
void *restrict  pIn1,
void *restrict  pIn2,
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_matMul_exec.

The function uses MMA hardware accelerator to perform the convolution computation. Filter data is loaded into B panel of the MMA from memory using one streaming engine, while the input data is loaded into A vectors of the MMA using the other streaming engine. Result of the compute from MMA C panel is stored into memory using a stream matMulress 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

◆ DSPLIB_matMul_exec_cn()

template<typename dataType >
DSPLIB_STATUS DSPLIB_matMul_exec_cn ( DSPLIB_kernelHandle  handle,
void *restrict  pIn1,
void *restrict  pIn2,
void *restrict  pOut 
)

This function is the main execution function for the natural C implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_matMul_exec.

Parameters
[in]handle: Active handle to the kernel
[in]pIn: Pointer to buffer holding the input data
[in]pFilterCoeffPointer to buffer holding the filter coefficient data
[in]pFilterVar: Pointer to buffer holding the filter variable data
[out]pOut: Pointer to buffer holding the output data
Returns
Status value indicating success or failure. Refer to DSPLIB_STATUS.

Definition at line 34 of file DSPLIB_matMul_cn.cpp.

◆ DSPLIB_matMul_init_cn()

DSPLIB_STATUS DSPLIB_matMul_init_cn ( DSPLIB_kernelHandle  handle,

DSPLIB_bufParams2D_t bufParamsIn1,
DSPLIB_bufParams2D_t bufParamsOut 
)

This function is the initialization function for the natural C implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_matMul_init.

Parameters

[out]bufParamsOut: Pointer to the structure containing dimensional information of ouput buffer
[in]pKerInitArgs: Pointer to the structure holding init parameters
Returns
