Abstract:
In this paper, we present a two-speed, radix-4, serial-parallel multiplier for accelerating applications such as digital filters, artificial neural networks, and other machine learning algorithms. Our multiplier is a variant of the serial–parallel (SP) modified radix-4 Booth multiplier that adds only the nonzero Booth encodings and skips over the zero operations, making the latency dependent on the multiplier value. Two sub circuits with different critical paths are utilized so that throughput and latency are improved for a subset of multiplier values. The multiplier is evaluated on an Intel Cyclone V field-programmable gate array against standard parallel–parallel and SP multipliers across four different process–voltage–temperature corners. We show that for bit widths of 32 and 64, our optimizations can result in a 1.42×–3.36× improvement over the standard parallel Booth multiplier in terms of area–time depending on the input set.

Base Paper Abstract:
Approximate computing is a promising technique to elevate the performance of digital circuits at the cost of reduced accuracy in numerous error-resilient applications. Multipliers play a key role in many of these applications. In this brief, we propose a truncation based Booth multiplier with a compensation circuit generated by selective modifications in k-map to circumvent the carry appearing from the truncated part. By judicious mapping, hardware pruning and output error reduction is achieved simultaneously. In the quest of power and accuracy trade-off, Truncated and Approximate Carry based Booth Multipliers (TACBM) are proposed with a range of designs based on truncation factor w. When compared with the state-of-the-art multipliers, TACBM outperforms in terms of accuracy and Area Power savings. TACBM (w = 10) provides with 0.02% MRED and 23% reduction in Area-Power product compared to exact Booth multiplier. The multipliers are evaluated using image blending and Multilayer perceptron (MLP) neural network and a high value of accuracy (95.63%) for MLP is achieved.

Base Paper Abstract:
Due to their shrinking feature sizes as well as environmental influences, such as high-energy radiation, electrical noise, and particle strikes, integrated circuits are getting more vulnerable to transient faults. Accordingly, how to make those circuits more robust has become an essential step in today’s design flows. Methods increasing the robustness of circuits against these faults already exist for a long period of time but either introduce huge additional logic, change the timing behavior of the circuit, or are applicable for dedicated circuits such as microprocessors only. In this paper, we propose an alternative method, which overcomes these drawbacks by determining application specific knowledge of the circuit, namely the relations of flip-flops and when they assume the same value. By this, we exploit partial redundancies, which are inherent in most circuits anyway (even the optimized ones), to frequently compare the circuit signals for their correctness—eventually leading to an increased robustness. Since determining the correspondingly needed information is a computationally hard task, formal methods, such as bounded model checking, satisfiability-based automatic test pattern generation, and binary decision diagrams, are utilized for this purpose. The resulting methodology requires only a slight increase in additional hardware, does only influence the timing behavior of the circuit negligibly, and is automatically applicable to arbitrary circuits. Experimental evaluations confirm these benefits.

Base Paper Abstract:
Convolutional Neural Network (CNN) has attained high accuracy and it has been widely employed in image recognition tasks. In recent times, deep learning-based modern applications are evolving and it poses a challenge in research and development of hardware implementation. Therefore, hardware optimization for efficient accelerator design of CNN remains a challenging task. A key component of the accelerator design is a processing element (PE) that implements the convolution operation. To reduce the amount of hardware resources and power consumption, this article provides a new processing element design as an alternate solution for hardware implementation. Modified BOOTH encoding (MBE) multiplier and WALLACE tree-based adders are proposed to replace bulky MAC units and typical adder tree respectively. The proposed CNN accelerator design is tested on Zynq-706 FPGA board which achieves a throughput of 87.03 GOP/s for Tiny-YOLO-v2 architecture. The proposed design allows to reduce hardware costs by 24.5% achieving a power efficiency of 61.64 GOP/s/W that outperforms the previous designs.
