Abstract
This work describes a floating-point arithmetic unit based on the CORD IC algorithm. The unit computes a full set of high level arithmetic an d elementary functions: multiplication, division, (co)sine, hyperbolic (co)sine, square root, natural logarithm, inverse (hyperbolic) tangen t, vector norm, and phase. The chip has been integrated in 1.6 mum dou ble-metal n-well CMOS technology and achieves a normalized peak perfor mance of 220 MFLOPS.
