Description: Verilog HDL: Magnitude
For a vector (a,b), the magnitude representation is the following:
A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.

Description: Among many types of the
motors, three-phase induction machines still enjoy the same unparalleled
popularity as they did a century ago. At least 90 of industrial drive
systems employ induction motors.
Most of the motors are uncontrolled, but the share of adjustable speed
induction motor drives fed from power electronic converters is steadily
increasing, phasing out dc drives. It is estimated that more than 50 billion
dollars could be saved annually by replacing all "dumb" motors with
controlled ones. However, control of induction machines is a much more
challenging task than control of dc motors. Two major difficulties are
the necessity of providing adjustable-frequency voltage (dc motors are
controlled by adjusting the magnitude of supply voltage) and the nonlinearity
and complexity of analytical model of the motor, aggrandized by
parameter uncertainty.

Description: The real and imaginary components of a complex Gabor filter are phase sensitive,
i.e., as a consequence their response to a sinusoid is another sinusoid (see Figure
1.2). By getting the magnitude of the output (square root of the sum of squared
real and imaginary outputs) we can get a response that phase insensitive and thus
unmodulated positive response to a target sinusoid input (see Figure 1.2). In some
cases it is useful to compute the overall output of the two out of phase filters.
One common way of doing so is to add the squared output (the energy) of each
filter, equivalently we can get the magnitude. This corresponds to the magnitude
(more precisely the squared magnitude) of the complex Gabor filter output. In the
frequency domain, the magnitude of the response to a particular frequency is simply
the magnitude of the complex Fourier transform, i.e.

Description: This paper proposes local Gabor XOR patterns (LGXP), which encodes the Gabor
phase by using the local XOR pattern (LXP) operator. Then, we in-troduce block-based Fisher’s linear discriminant (BFLD) to reduce
the dimensionality of the proposed descriptor and at the same time
enhance its discriminative power.
