DFPAU-DP

DFPAU-DP www.DataSheet4U.com Floating Point Arithmetic Coprocessor Double Precision ver 3.02 OVERVIEW DFPAU-DP is a technology independent design that can be implemented in a variety of process technologies. DFPAU-DP is a Floating Point Arithmetic Coprocessor, designed to assist CPU in performing the floating point arithmetic computations. DFPAU-DP directly replaces C software functions, by equivalent, very fast hardware operations, which significantly accelerate system performance. It doesn’t require any programming, so it also doesn’t require any modifications made in the main software. Everything is done automatically during software compilation by the DFPAU-DP C driver. DFPAU-DP was designed to operate with DCD’s DP8051, but can also operate with any other 8-, 16- and 32-bit processor. Drivers for all popular 8051 C compilers are delivered together with the DFPAU-DP package. DFPAU-DP uses the specialized algorithms to compute math functions. It supports addition, subtraction, multiplication, division, square root, and comparison. It has built-in conversion instructions from integer type to floating point type and vice versa. The input numbers format is according to IEEE-754 standard. DFPAU-DP supports double and single precision real numbers, 8-bit, 16-bit and 32-bit integers. DFPAU-DP is prepared to use with 8-, 16- and 32-bit processors. Each floating point function can be turned on/off at configuration level providing the flexible scalability of DFPAU-DP module. It a...
