Trigonometric functions are often used in embedded systems. Motor drivecontrol applications such as the Park Transform, Clarke Transform, andPWMgeneration use trigonometric functions extensively.

Digital signal processors (DSPs) crunch the numbers for applications that require fast analog-to-digital-to-analog conversion, such as software-defined radio and radar. If you weren't using a DSP, you ...

Most engineers tasked with implementing a mathematical function such as sine, cosine or square root within an FPGA may initially think of doing so by means of a lookup table, possibly combined with ...

The arithmetic unit is one of the important components of CPU design. For computation of complex arithmetic functions on hardware, the CORDIC algorithm is an attractive fixed-point algorithm that uses ...
