What is CORDIC used for?

The CORDIC (Coordinate Rotation Digital Computer) algorithm are used for the rapid calculation associated with elementary operates like trigonometric function, multiplication, division and logarithm function, and also various conversions such as conversion of rectangular to polar coordinate including the conversion …

How does CORDIC algorithm work?

1.3 How does it work? CORDIC revolves around the idea of “rotating” the phase of a complex number, by multiplying it by a succession of constant values. However, the multiplies can all be powers of 2, so in binary arithmetic they can be done using just shifts and adds; no actual multiplier is needed.

How do you use CORDIC?

The basic idea behind the CORDIC algorithm is that we can string many of these rotation matrices together–either rotating by a positive theta_k or a negative theta_k in each matrix. As an example, suppose you rotated [1, 0] by +26.57 degrees (k=1), then by 14.03 degrees (k=2), then backwards by 7.12 degrees (k=3).

How does a computer compute sine?

A calculator or computer program is not reading off of a list, but is using an algorithm that gives an approximate value for the sine of a given angle. For example, to find out sine 23, first convert 23 to radians by dividing it by 180 and then multiplying by π.

How is sine implemented in C?

C Language: sin function (Sine)

1. Syntax. The syntax for the sin function in the C Language is: double sin(double x);

What is the sin at 0?

The exact value of sin(0) is 0 .

What is an example of CORDIC algorithm?

CORDIC. CORDIC (for CO ordinate R otation DI gital C omputer), also known as Volder’s algorithm, is a simple and efficient algorithm to calculate hyperbolic and trigonometric functions, typically converging with one digit (or bit) per iteration. CORDIC is therefore also an example of digit-by-digit algorithms.

What does CORDIC stand for?

CORDIC (for COordinate Rotation DIgital Computer), also known as Volder’s algorithm, is a simple and efficient algorithm to calculate hyperbolic and trigonometric functions, typically converging with one digit (or bit) per iteration.

What is the advantage of using CORDIC over other approaches?

CORDIC is generally faster than other approaches when a hardware multiplier is not available (e.g., a microcontroller), or when the number of gates required to implement the functions it supports should be minimized (e.g., in an FPGA or ASIC ).

What is the CORDIC block?

Initially CORDIC was used for circular co-ordinates but later it is extended for linear and hyperbolic co-ordinates. In each co-ordinate system both the modes are possible. Depending upon the mode of operation CORDIC block evaluates various functions.
