Graph Conversion - 2025.2 English - UG1079

Connect statements with buffer port to buffer port do not require template parameters specifying the size. Use dimensions() API in graph to specify number of samples (not bytes) for all input/output buffer ports. You can specify buffer port size (number of samples, not bytes) using kernel function prototypes when the dimensions() APIs in graph are not used.

Window-Based Connect Example

connect<window<EQ24_INPUT_SAMPLES*4, EQ24_INPUT_MARGIN*4> > (in.out[0], eq24.in[0]);
connect<window<HB27_2D_INPUT_SAMPLES*4, HB_2D_INPUT_MARGIN*4> > (eq24.out[0], hb27.in[0]) ;
connect<window<HB27_2D_INPUT_SAMPLES*4, HB_2D_INPUT_MARGIN*4> > (eq24.out[1], hb27.in[1]) ;
connect<window<CE_INPUT_SAMPLES*4, CE_INPUT_MARGIN*4> > (hb27.out[0], ce.in[0]) ;

Buffer Port-Based Connect and Dimensions Example

connect(in.out[0], eq24.in[0]) ;
connect(eq24.out[0], hb27.in[0]) ;
connect(eq24.out[1], hb27.in[1]) ;
connect(hb27.out[0], ce.in[0]);
adf::dimensions(eq24.in[0]) = { EQ24_INPUT_SAMPLES };
adf::dimensions(hb27.in[0]) = { HB27_2D_INPUT_SAMPLES };
adf::dimensions(hb27.in[1]) = { HB27_2D_INPUT_SAMPLES };
adf::dimensions(eq24.out[0]) = { EQ24_OUTPUT_SAMPLES };
adf::dimensions(eq24.out[1]) = { EQ24_OUTPUT_SAMPLES };
adf::dimensions(hb27.out[0]) = { HB27_2D_OUTPUT_SAMPLES };
adf::dimensions(ce.in[0]) = { CE_INPUT_SAMPLES };
