xfblasStatus_t xfblasGetVector(int n, int elemSize, short* d_x, short* x, int incx, unsigned int kernelIndex = 0, unsigned int deviceIndex = 0) xfblasStatus_t xfblasGetVector(int n, int elemSize, float* d_x, float* x, int incx, unsigned int kernelIndex = 0, unsigned int deviceIndex = 0)
This function copies a vector in FPGA device memory to host memory.
Parameters:
| n | number of elements in vector |
| elemSize | number of bytes required to store each element in the vector |
| d_x | pointer to mapped memory |
| x | pointer to the vector in the host memory |
| incx | the storage spacing between consecutive elements of vector x |
| 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 | 3 if there is no FPGA device memory allocated for the vector |
