Posit Based-Processor


The Posit Based Processor design has a circuit that is much simpler, silicon efficient, and high performance. Our PNU performs addition, subtraction, multiplication, division, square root, and other operations about 4X faster than with respect to state-of-the-art FPUs. These operations are quite frequent in FP applications.

Floating Point (FP) arithmetic has become more widespread in wireless communications, military applications, aeronautical applications, 3D graphics simulations, aircraft design, and signal processing. However, the FP number system provides a less accurate, less dynamic range, and more exceptions resulting in complicated Floating Point Unit (FPU) and power greedy processors. On other hand, the POSIT number system offers much better accuracy, better dynamic range, and fewer exception at half data width with respect to the FP number system.
