42.5.1 Image Data Snoop (IDS) Controller
The Image Data Snoop Controller allows packet monitoring for system-level bring up and debug. When a new image data packet is received, a new entry is created. An entry is composed of the data type, the virtual channel identifier, the word count and the row count. When a new packet with the same virtual channel identifier and data type is received, the row count field is incremented. The table of entry is transferred at the end to the user interface for processor analysis.
