NTX is the name given to a hardware accelerator that ETH Zurich has developed for floating-point arithmetic. With 260 Gflops / W, the chip implemented in 22nm FD-SOI offers unmatched energy efficiency and beats every competitor by far. Eight NTX units are controlled by an RV32IMC RISC V-Core, which provides full software flexibility. A key feature is a focus on eliminating the bottleneck common to Neumann architectures by amortizing RISC-V instructions across eight NTX units and removing all FP load/store operations from the instruction stream through the AGUs.
