A CMOS floating-point vector-arithmetic unit

This work describes a floating-point arithmetic unit based on the CORDIC algorithm. The unit computes a full set of high level arithmetic and elementary functions: multiplication, division, (co)sine, hyperbolic (co)sine, square root, natural logarithm, inverse (hyperbolic) tangent, vector norm, and phase. The chip has been integrated in 1.6 fm double-metal, n-well CMOS technology and achieves a normalized peak performance of 220 MFLOPS.
