Ever heard of GPUs that can be programmed on the fly? VividSparks, a company from Hubli, Karnataka, is working on making this possible. Dr Vijay Holimath, President and CEO of VividSparks, talks about how the company brought a revolution in the computing world.

High-end computing technology needs to be efficient and powerful, but using a floating point number system makes it challenging to accomplish. This is due to the requirement for double precision in a floating point number system for good arithmetic accuracy. Thanks to the POSIT numbering system VividSparks has developed a novel chip based cloud computing technology that enables the programming of both the hardware and the software. This way, next-generation processors can perform complicated tasks in high-performance computing efficiently.

The POSIT number system supports technology that avoids mathematical overflows or underflows and assists in a high dynamic range. Hence, good efficiency conveys highly accurate detection correction algorithms and good mathematical results.

Dr Vijay Holimath says, “The POSIT number system in computing technology can make the chip smaller, and whatever you implement on the chip will be cheaper. The carbon footprint is lower, and this also reduces power consumption.” VividSparks introduced the first POSIT number based GPGPUs (general-purpose GPUs) and compilers that implement super-fast arithmetic libraries.
