Various steps involved in the development of hardware required for performing fixed-point binary division with low power, low area and high speed are discussed. Restoring division algorithm supported subtraction
A fixed-point number has a decimal point, but the decimal point is fixed. For example, if dealing with money, there is no need for more than two decimal points. The number can be saved like an integer and tell the compiler to always remember there is a decimal point before the last ...
Furthermore, the fixed-point divider is extended to support IEEE 754-2008 compliant decimal floating-point division for decimal64 data format. Finally, the algorithms have been synthesized on a Xilinx Virtex-5 FPGA, and implementation results are given. 1. Introduction Many applications, particularly...
Lastly, let’s look at fixed-point division. We want to divide twoQ m. nnumbers,xbyy, and return a quotient that is also aQ m. nnumber. This means we want an integer that representsX∕Yscaled by 2n. This is what we get if we implement the following algorithm, ...

blocks using HDL Coder™. The Fixed-Point Designer library of functions include CORDIC-based and other hardware-efficient implementations of math operations such as division, exponential operations, and trigonometric functions. Use coder to generate C/C++ code for designs that incorporate these ...
Ifbis a multiplication or division operation with a fixed-point operand andais a fixed-point data object, then the constant has the type that provides the best possible precision for a fixed-point result. As an argument in a function call, the constant has the same type as the formal argum...

The algorithm based on fixed-point iteration (Eq. 2.115), a natural approach within the DA framework, can outperform the integrator discussed in the previous section in speed, especially for ODEs for which the right-hand sides consist of a large number of arithmetic operations. Similar to the ...
For fixed-point input u, fixed.cordicReciprocal wraps on overflow for division by zero. The behavior for fixed-point division by zero is summarized in the table below. Wrap OverflowSaturate Overflow 0/0 = 0 0/0 = 0 1/0 = 0 1/0 = upper bound -1/0 = 0 -1/0 = lower bound For...
