Video and Image Processing Up Conversion Example Design

Review the System Integration Using SOPC Builder
The video up conversion data path module (which is located in
DSPBuilder Systems > example_design_data_path_Interface) refers to
the synthesizable section of the DSP Builder system described in the
previous section. (see Figure 38).
It provides the following interfaces:
■ Two Avalon-ST data interfaces:
● The Avalon_ST_Sink interface inputs the image pixels into
the data path
● The Avalon_ST_Source interface outputs the processed
image stream
■ Two Avalon-MM control interfaces:
● The read master interface (Avalon_MM_Read_Master) to read
data from the external DDR2 memory
● The write master interface (Avalon_MM_Write_Master) to
write data to the external DDR2 memory
