14.12 INTERPOLATOR DAG FOR s₁ = [1 0]

The DAG corresponding to s₁ is shown in Fig. 14.13. The equitemporal planes are indicated by the gray lines and the time index values are indicated by the grayed numbers associated with the equitemporal planes. We note from the figure that a maximum of four tasks or nodes is active at any time step. It should also be noted that the time values are associated with the high data rate of the interpolator output. We have three possible valid projection vectors:
