Control Path

While the datapath is the path on which computations occur, the control path is the path of signals that control the datapath circuitry.

The control path is the logic added by the compiler to manage the flow of data through your design. Control paths include controls such as the following:

Control Description
Handshaking flow control

Handshaking ensures that one part of your design is ready and able to accept data from another part of your design.

Loop control

Loop controls control the data flow through the hardware generated for loops in your code, including any loop carried dependencies.

Branch control

Branch controls implement conditional statements in your code. Branch control can include parallelizing parts of conditional statements to improve performance.
