A DSP Double Data Rate (DDR) technique is used to improve the performance achieved with the device. Therefore, two input clocks for the DPU are needed: One for general logic and another at twice the frequency for DSP slices. The difference between a DPU not using the DSP DDR technique and a DPU enhanced usage architecture is shown here.

Note: All DPU architectures referred to in this document refer to DPU enhanced usage, unless otherwise specified.
