template < typename T1, typename T2, typename T3, typename T_O, T_O(*)(T1, T2, T3) opf > void staticEval ( hls::stream <T1>& in1_strm, hls::stream <T2>& in2_strm, hls::stream <T3>& in3_strm, hls::stream <bool>& e_in_strm, hls::stream <T_O>& out_strm, hls::stream <bool>& e_out_strm )
Three stream input static evaluation.
static_eval function calculate the experssion result that user defined. This result will be passed to aggregate module as the input. When calling this API, the T1 T2 T3 T_O are the input/output data types for each parameter of user code. E.g.
// decl
long user_func(int a, int b, int c);
// use
database::static_eval<int, int, int, long, user_func>(
in1_strm, in2_strm, in3_strm, e_in_strm,
out_strm, e_out_strm);
In the above call, three int are the data type of input of user_func , and long is the return type of user_func .
Parameters:
| T1 | the input stream type, inferred from argument |
| T2 | the input stream type, inferred from argument |
| T3 | the input stream type, inferred from argument |
| T_O | the output stream type, inferred from argument |
| opf | the user-defined expression function |
| in1_strm | input data stream |
| in2_strm | input data stream |
| in3_strm | input data stream |
| e_in_strm | end flag stream for input data |
| out_strm | output data stream |
| e_out_strm | end flag stream for output data |
