PACoGen: Posit Arithmetic Core Generator


A parameterized Verilog HDL posit arithmetic core generator is developed for posit arithmetic (adder, multiplier and division arithmetic). These generators support the posit standard including rounding to nearest rounding method and can be used to generate the Verilog HDL for any combination of Word-Size (N) and Exponent-Size (ES).

This work is based on folowing articles, but primarily on [1]. Please refer them for more detailed description of PACoGen.
