Digital Core Design today announces the release of a Double Precision Floating Point CoprocessorMay 10, 2006 - Digital Core Design, the Intellectual Property (IP) provider, today announces the release of a DFPMU-DP – Double Precision Floating Point Coprocessor. The DFPMU-DP is a 64-bit Double Precision Floating Point Coprocessor, designed to assist CPU in performing the IEEE754 single and double precision floating point mathematic computations. The DFPMU-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 main software. Everything is done automatically during software compilation by the DFPMU-DP C Driver. The DFPMU-DP 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-DP package. The DFPMU-DP supports also a popular 32 Bit processors: NIOS II and MicroBlaze, and the C drivers for those processors are delivered with the DFPMU-DP for free. The DFPMU-DP uses the specialized CORDIC and standard algorithms to compute math functions. The DFPMU executes 21 operations in such a groups as:
Each floating point function can be turned on/off at configuration level providing the flexible scalability of DFPMU-DP module. It allows to save silicon space and provides exact configuration required by a certain application. DFPMU-DP is a technology independent design that can be implemented in a variety of process technologies, in applications such as:
Typical system performance improvement for 32-Bit RISC Processors system (NIOS II / MicroBlaze) is 55 times.
