This intellectual property (IP) family presents new designs for decimal floating point (DFP) addition, multiplication, fused multiply-add, division, and square root. All the IP cores are using the IEEE 754-2008 Decimal Interchange format encoding, and most of them support both decimal64 (16 digits) and decimal128 (34 digits) formats. We areconstantly working on designing and implementing hardware IP cores for decimal floating-point arithmetic. We aims to promote the development of computer arithemtic with high standard, reliable and cost effective decimal arithmetic cores, which can be flexibly extended and verified for the technology industrial.
