Transition to Next Generation Arithmetic is in the horizon !

The emerging posit data type (unum type 3) is proving advantageous in HPC, signal processing, Machine Learning, Big Data, and a broad range of data center applications, since it provides better answers using fewer bits. Lot of research has been done to discover the advantages of Posits and many papers have been published. European Processor Initiative (EPI) has announced that they will be using posit arithmetic in their accelerator boards used for their supercomputer centre design.

CalligoTech has been the pioneer in commercialization of posit arithmetic, both hardware and software, since posits were introduced in 2017. Posit Numeric Unit (PNU) - a Posit-based Co-Processor functionality was demonstrated at Supercomputing Asia. We then integrated our PNU with RISC-V Processor to build and demonstrate world’s first Posit-enabled RISC-V core (CRISP) at RISC-V summit in Switzerland.

Introducing TUNGA – world’s first multi-core RISC-V with Posits !

TUNGA (name of a river in Southern part of India) is an SoC with multiple CRISP-cores built to accelerate HPC and AI workloads with Posit as the fundamental enabling technology for real-number computations. Each core comes with QUIRE – a fixed-point accumulator structure that produces exact dot products guaranteed up to ~2 billion-long vectors (231).
