What is VividarithmetiK?
VividarithmetiK is a next generation arithmetic co-processor that computes basic arithmetic functions such as addition, subtraction, multiplication, division, square root, trigonometric functions, compare and convert instructions using a new number system called POSIT, that is highly silicon efficient and brilliant performing. VividarithmetiK has a family of processors called Supersonik, Racer, Falkon and Tez with different POSIT configurations specifically targeted towards HPC, Graphics, AI and Automotive applications respectively.
VividarithmetiK eliminates carry propagation in adders and multipliers using novel adder called Carry Free Adder (CFA). CFA not only eliminates carry propagation but also consumes very less power. We build top performing chips by implementing super-fast arithmetic libraries in them rather than fabricating chip in higher technology nodes.
