- In the process of scientific computing, digital signals processing, communication and image processing, division and square root are the widely used basic operation. This article designs a unit of floating-point division and square root based on SRT4 algorithm. It reduces the iterative division and square root calculation delay by using parallel processing of quotient and residue addition and the on-the-fly conversion technology. At the same time, it reduces hardware resources and saves area by adopting reuse the lookup table and the adder. Experiments show that the cell area is 9812.3087um2, the power is 10.7854mW, the cycles per division instruction is 31, the cycles per square root instruction is 28, comprehensive frequency up to 2.5GHz with 40nm technology library and the timing constraint 400ps.
