template <typename t_DataType, unsigned int t_LogParEntries, typename t_IndexType = unsigned int> void asum(unsigned int p_n, hls::stream<WideType<t_DataType,(1<<t_LogParEntries)>>& p_x, t_DataType& p_sum)
asum function that returns the sum of the magnitude of vector elements.
Parameters:
| t_DataType | the data type of the vector entries |
| t_LogParEntries | log2 of the number of parallelly processed entries in the input vector |
| t_IndexType | the datatype of the index |
| p_n | the number of entries in the input vector p_x, p_n % l_ParEntries == 0 |
| p_x | the input stream of packed vector entries |
| p_sum | the sum, which is 0 if p_n <= 0 |
