We are always excited when we see [Hamster] post an FPGA project, because it is usually something good. His latest post doesn’t disappoint and shows how he uses the CORDIC algorithm to generate very ...

Abstract: This paper presents the uniformly distributed (UD) coordinate rotation digital computer (CORDIC). It receives this name because the distance between its rotation angles is uniform. The paper ...

CORDIC (COordinate Rotation DIgital Computer) is an iterative algorithm which is used to calculate trignometric functions, vector rotations, complex multiplication and division, hyperbolic functions ...

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 ...

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

Abstract: The COordinate Rotation DIgital Computer(CORDIC) is a well known special purpose algorithm to compute various complex mathematical functions. Since CORDIC has less hardware complexity, it ...

第3弾ということで、ここまでの詳細は を、確認いただければと思います。 で今回の本題ですが、 三角関数はCORDICアルゴリズムで実装したので、逆三角関数も使えるようにしたいと思って検討した結果、テーラー展開にて実装しようと思い立ち、係数に ...
