The AI Engine array is made up of AI Engine tiles and AI Engine array interface tiles (the last row of the array). The
types of interface tiles include the AI Engine to PL and AI Engine to NoC interface
tiles. There is also exactly one configuration interface tile in each AI Engine array that contains a PLL for AI Engine clock generation and other global
control functions. The following figure shows a conceptual view of the complete tile
hierarchy associated with the AI Engine
array. See AI Engine Tile Architecture and AI Engine Array Interface Architecture for detailed descriptions of the various tiles.
