10.1. ALU Folding
ALU folding reduces the resource consumption of a design by as much as it can while still meeting the latency constraint. The constraint specifies the maximum number of clock cycles a system with folding takes to process a packet. If ALU folding cannot meet this latency constraint, or if ALU folding cannot meet a latency constraint internal to the DSP Builder system due to a feedback loop, you see an error message stating it is not possible to schedule the design.
