This assembly code demonstrates Binary-Coded Decimal (BCD) arithmetic operations using the aas (ASCII Adjust for Subtraction) instruction. BCD is a binary-encoded representation of decimal values that ...

Editor's Note: This is the first article in a two-part series on decimal representations and decimal arithmetic in general, and on Binary Coded Decimal (BCD) in particular. In this first installment, ...

This project is a low-level implementation of an Arithmetic Logic Unit (ALU) written entirely in Verilog HDL. It focuses on providing fundamental arithmetic functionalities such as addition, ...

If you ask engineers how numbers are represented, stored and manipulated in computers and calculators, most will reply “as signed or unsigned binary integers” or “as fixed-point or floating-point ...

Abstract: IEEE 754r is the ongoing revision to the IEEE 754 floating point standard. A major enhancement to the standard is the addition of decimal format, thus the design of BCD arithmetic units is ...

Abstract: This paper presents a formal design of decimal arithmetic circuits using an arithmetic description language called ARITH. The use of ARITH makes possible (i) formal description of arithmetic ...
