Architecture is optimized for adder subtractors and other resources hence demonstrating very low gate count of only 22k.
High Speed Low Power Complex Multiplier Design Using Parallel Adders and Subtractors, International Journal on Electronic and Electrical Engineering (IEEE), 7(2): 3846.
In the FFT algorithm, the complex floating point add, subtract, and multiply operations shown in figure 1 can be realized with a discrete implementation that uses three reversible single precision floating point adders to perform the complex add and four reversible single precision floating point multipliers and three reversible single precision floating point subtractors to perform the complex subtract.
The definition of total complexity is the sum of the number of adders, subtractors, and multipliers.
However, it should be noted that it is not always necessary to use the above technique and the Walsh transform (WT) may be performed just by using adders and subtractors [6].
Like in the UK the vast majority are harmless but they do have adders (apparently the subtractors left years ago!) which are venomous.
After explaining finite field operations they describe hardware platforms such as instruction set processors, ASIC designs, hardware description languages and programmable logic, general principles of circuit synthesis, adders and subtractors, multipliers, dividers and other arithmetic operators, circuits for finite field operations and floating-point units.
Many of these operations are "value subtractors," manufacturing unsalable products out of valuable raw materials and labor that in a free economy would be liberated for truly productive uses.
A dynamic-error system (4) can be expressed using the integrators and four-fundamental arithmetical operations, including adders, subtractors, and multipliers.
Therefore, the number of adders and subtractors used to generate weighting coefficients in this method are much less than the bi-cubic algorithm [16].
The hardware computes the exponent of the logarithmic function in (3c) with an adder and two subtractors. The second subtractor is needed to ensure the calculation of the absolute value of the difference (v - [v.sub.ref]) in case v has a decrementing behaviour and hence is smaller than its reference value.
The implementation of full adder and subtractor as the major component of the arithmetic procedures can precisely influence the functioning of the entire architecture.
