template <typename t_DataType, unsigned int t_ParEntries, typename t_IndexType = unsigned int> void scal(unsigned int p_n, t_DataType p_alpha, hls::stream<WideType<t_DataType, t_ParEntries>>& p_x, hls::stream<WideType<t_DataType, t_ParEntries>>& p_res)
The scal function that compute X = alpha * X.
Parameters:
| t_DataType | The data type of the vector entries. |
| t_ParEntries | Number of parallelly processed entries in the packed input vector stream. |
| t_IndexType | The datatype of the index. |
| p_n | The number of entries in vector X, p_n % t_ParEntries == 0. |
| p_x | The packed input vector stream. |
| p_res | The packed output vector stream. |
