Floating point computation is only accurate to 6 decimal places in 32-bit single precision, or to 16 decimal places in 64-bit double precision. Values beyond that are rounded or truncated.
The POSIT universal number system, or unum, is more accurate than single precision floating point by 2 decimal places, and by 3 decimal places over double precision.
With the POSIT unum, you will achieve a higher dynamic range, and the accuracy of your computations will improve by 2 or 3 decimal places. This is particularly significant when carrying the result of one computation into the next, as the inaccuracy of the floating point computation becomes exponential.
There are a handful of academic open source implementations of POSIT, but VividSparks’s embodiment as a soft IP core represents decades of refinement of the number system for commercial, industrial, and research applications.
VividSparks extracts unmatched power and performance from your hardware. The higher dynamic range means less silicon for the same application, combined with higher computational accuracy from the POSIT number system versus Floating Point.
Applications include HPC High Performance Computing, Graphics, Machine Learning, Artificial Intelligence, DSP digital signal processing, audio and video.
Zerif Technologies Ltd. of London, England, provides advanced electronics products for science and industry, and is an international distributor for VividSparks POSIT. Zerif is a wholly owned subsidiary of Sky Blue Microsystems GmbH of Munich, Germany, founded in 1999.
Vivid Sparks is delivered in the most flexible and economical form of your choice:
VividSparks soft IP core is delivered with an API that is embedded in your source code that calls the VividSparks IP to perform computations, as required. You can think of this as a virtual math co-processor, “virtual” is that it is incorporated in your design and code rather than as external hardware, and “math co-processor” in that it performs your computations faster, more exactly, and more efficiently than any other hardware.
VivdSparks has implemented a full range of operations using CFA Carry Free Addition, including:
