Query: NTX: An Energy-efficient Streaming Accelerator for Floating-point
  Generalized Reduction Workloads in 22nm FD-SOI   Specialized coprocessors for Multiply-Accumulate (MAC) intensive workloads
such as Deep Learning are becoming widespread in SoC platforms, from GPUs to
mobile SoCs. In this paper we revisit NTX (an efficient accelerator developed
for training Deep Neural Networks at scale) as a generalized MAC and reduction
streaming engine. The architecture consists of a set of 32 bit floating-point
streaming co-processors that are loosely coupled to a RISC-V core in charge of
orchestrating data movement and computation. Post-layout results of a recent
silicon implementation in 22 nm FD-SOI technology show the accelerator's
capability to deliver up to 20 Gflop/s at 1.25 GHz and 168 mW. Based on these
results we show that a version of NTX scaled down to 14 nm can achieve a 3x
energy efficiency improvement over contemporary GPUs at 10.4x less silicon
area, and a compute performance of 1.4 Tflop/s for training large
state-of-the-art networks with full floating-point precision. An extended
evaluation of MAC-intensive kernels shows that NTX can consistently achieve up
to 87% of its peak performance across general reduction workloads beyond
machine learning. Its modular architecture enables deployment at different
scales ranging from high-performance GPU-class to low-power embedded scenarios.
