FISR

Specialized FPU for Fast Inverse Square Root Algorithm

---

Got inspired from this video!
I might think it would be easy to understand what we did if you watch the above video.

FISR algorithm computes the inverse square root( $y = {{1}\over {\sqrt x}}$ ) 4 times faster than traditional methods with IEEE floating point tricks.

We have succeeded in implementing this algorithm as digital circuits using Verilog. Hope you enjoy viewing our work!
