Digital Core Design Announces Availability of a New Improved DFPMU Floating Point Coprocessor
- Digital Core Design, the Intellectual Property (IP) provider, today has announced the release of a new – improved DFPMU – Floating Point Coprocessor.
The DFPMU is a Floating Point Coprocessor, designed to assist CPU in performing the floating point mathematical computations. The DFPMU directly replaces C software functions, by equivalent , very fast hardware operations, which significantly accelerate system performance. It neither doesn’t requires any programming, nor modifications made in main software. Everything is done automatically during software compilation by the DFPMU C Driver.
DFPMU was designed to operate with DCD’s DP8051/DP80390 microcontrollers, 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.
The DFPMU executes 15 operations in such groups as:
- arithmetic functions,
- trigonometric functions,
- comparison functions,
- data conversion.
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 to save silicon space and provides exact configuration required by certain application.
DFPMU is a technology independent design that can be implemented in a variety of process technologies.
The DFPMU can improve the 8051 based system performance up to 162 times, compared to the same application, running on the standard 80C51, without coprocessor.
New DFPMU can be used in such applications as:
- math coprocessors
- DSP algorithms
- embedded arithmetic coprocessor
- fast data processing & control.
