- AI Engine
- Each AI Engine is a very long instruction word (VLIW) processor containing a scalar unit, a vector unit, two load units, and a single store unit.
- AI Engine Tile
- An AI Engine tile contains an AI Engine, a local memory module together with several communication paths to facilitate data exchange between tiles.
- AI Engine Array
- The AI Engine array consists of a 2D array of AI Engine tiles, where each AI Engine tile contains an AI Engine, memory module, and tile interconnect module.
- AI Engine Program
- The AI Engine program consists of a data flow graph specification which is written as a C++ class. A top-level program will instantiate one or more graph classes and will be compiled and executed using the AI Engine tool chain.
- AI Engine Kernels
- Kernels are written in C/C++ using AI Engine vector data types and intrinsic functions. These are the computation functions running on an AI Engine. The kernels form the fundamental building blocks of a data flow graph specification.
- ADF Graph
- An ADF graph is a network with a single AI Engine kernel or multiple AI Engine kernels connected by data streams. It interacts with
the programmable logic, global memory, and processing system with specific
constructs like PLIO (port attribute in the graph that is used to make
stream connections to or from the programmable logic), GMIO (port attribute
in the graph that is used to make external memory-mapped connections to or
from the global memory), and RTP.
Graphs can also be embedded into other graphs as sub-graphs, which allows for structuring the design into logical subsystems.
