5 Summary

The differentiation provided by the Texas Instruments Fast Integer Division (FID) unit reduces the latency of different division operations. The FID unit provides several folds improvement in performance for different types of division operations. The cycles saved for division operation along with the many of the other differentiations provided in C2000 devices such as FPU, TMU and the inherent C28x DSP minimizes the latency of control loop calculations and opens up usage in new applications. The intrinsics support in compiler ensures that the use of this differentiation is just a few additional lines of code.
