16-bit Cosine Function

16-bit Cosine Function 

General Description

Function y = cos(x) calculates the cosine of an angle in radians. It has a high-speed, fully pipelined architecture and uses a polynomial with dynamic coefficients to calculate the result to within 0.0002. Input and output values are 16-bit unsigned fractions.

Key Design Features

- Function y = cos(x)
- Input range between 0 and Pi/2 radians
- Output range between 0 and 1
- Quadratic polynomial with dynamic coefficients
- Input values as 16-bit unsigned fractions
- Output values as 16-bit unsigned fractions
- Accurate to within 0.0002
- High-speed fully pipelined architecture
- 3 clock-cycle latency

Cos x function

Applications

- Fixed-point mathematics
- Quadrature signal generation in digital comms
- Alternative to using a 64k x 16-bit LUT
- Cheaper than a CORDIC solution
