xfblasStatus_t xfblasSetMatrix(int rows, int cols, int elemSize, short* A, int lda, short* d_A, unsigned int kernelIndex = 0, unsigned int deviceIndex = 0) xfblasStatus_t xfblasSetMatrix(int rows, int cols, int elemSize, float* A, int lda, float* d_A, unsigned int kernelIndex = 0, unsigned int deviceIndex = 0)
This function copies a matrix in host memory to FPGA device memory. xfblasMalloc() need to be called prior to this function.
Parameters:
| rows | number of rows in the matrix |
| cols | number of cols in the matrix that is being used |
| elemSize | number of bytes required to store each element in the matrix |
| A | pointer to the matrix array in the host memory |
| lda | leading dimension of the matrix that indicates the total number of cols in the matrix |
| d_A | pointer to mapped memory |
| kernelIndex | index of kernel that is being used, default is 0 |
| deviceIndex | index of device that is being used, default is 0 |
Return:
| xfblasStatus_t | 0 if the operation completed successfully |
| xfblasStatus_t | 1 if the library was not initialized |
| xfblasStatus_t | 2 if parameters rows, cols, elemSize, lda <= 0 or cols > lda or data types are not matched |
| xfblasStatus_t | 3 if there is no FPGA device memory allocated for the matrix |
| xfblasStatus_t | 4 if the engine is not supported for now |
