WebFeb 10, 2012 · So the first step of the algorithm is to start with an initial guess for 1/D which we call X_0. X_0 is defined as X_0 = 48/17-39/17*D However, we must first apply a bit-shift to the divisor D to scale it so that 0.5 ≤ D ≤ 1. The same bit-shift should be applied to the numerator N so that the quotient does not change.

WebMar 15, 2012 · The basic idea is to use regular integer types to represent fractional values. Fixed-point math is most commonly used for systems that lack an FPU or when you need a few more ounces of performance or precision than the standard floating point types can provide (hint: this is rare). WebCORDIC. CORDIC is an acronym for COordinate Rotation DIgital Computer. The Givens rotation-based CORDIC algorithm is one of the most hardware-efficient algorithms available because it requires only iterative shift-add operations (see References). The CORDIC algorithm eliminates the need for explicit multipliers.
