Query: Reconfigurable co-processor architecture with limited numerical
  precision to accelerate deep convolutional neural networks   Convolutional Neural Networks (CNNs) are widely used in deep learning
applications, e.g. visual systems, robotics etc. However, existing software
solutions are not efficient. Therefore, many hardware accelerators have been
proposed optimizing performance, power and resource utilization of the
implementation. Amongst existing solutions, Field Programmable Gate Array
(FPGA) based architecture provides better cost-energy-performance trade-offs as
well as scalability and minimizing development time. In this paper, we present
a model-independent reconfigurable co-processing architecture to accelerate
CNNs. Our architecture consists of parallel Multiply and Accumulate (MAC) units
with caching techniques and interconnection networks to exploit maximum data
parallelism. In contrast to existing solutions, we introduce limited precision
32 bit Q-format fixed point quantization for arithmetic representations and
operations. As a result, our architecture achieved significant reduction in
resource utilization with competitive accuracy. Furthermore, we developed an
assembly-type microinstructions to access the co-processing fabric to manage
layer-wise parallelism, thereby making re-use of limited resources. Finally, we
have tested our architecture up to 9x9 kernel size on Xilinx Virtex 7 FPGA,
achieving a throughput of up to 226.2 GOp/S for 3x3 kernel size.
