8-bit sequential square root extractor

Input

8-bit Number, Extraction Button

Output

4-bit Square Root, 5-bit Remainder

Speed

Total of 71 rTicks after button press

Notes

Once the button is pressed, it takes 2 ticks to initiate the circuit. The Square Root is saved 4 rTicks after the Remainder, and the circuit is cleared for 1 cycle, 1 rTick after the Root is saved. 1 cycle lasts 13 rTicks, so it takes 8t for init, 4 clock cycles, and 11 ticks to finish saving and clearing. This uses a Non-restoring / trial subtraction Binary Digit-by-Digit Square Root Algorithm.
