05 OVERVIEW DFPMU is a technology independent design that can be implemented in a variety of process technologies.
DFPMU is a Floating Point Coprocessor, designed to assist CPU in performing the floating point mathematic computations.
DFPMU 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 DFPMU C driver.
DFPMU 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 DFPMU package.
DFPMU uses the specialized CORDIC and standard algorithms to compute math functions.
It supports addition, subtraction, multiplication, division, square root, comparison, absolute value, change sign of a number and trigonometric functions: sine, cosine, tangent and arctangent.
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.
DFPMU supports single precision real numbers, 16-bit and 32-bit integers.
Each floating point function can be turned on/off at configuration level providing the flexible scalability of DFPMU module.
It allows save silicon space and provides exact configuration required by certain application.
