text: 'Approximate circuits trade-off computational accuracy against improvements
in hardware area, delay, or energy consumption. IP core vendors who wish to create
such circuits need to convince consumers of the resulting approximation quality.
As a solution we propose proof-carrying approximate circuits: The vendor creates
an approximate IP core together with a certificate that proves the approximation
quality. The proof certificate is bundled with the approximate IP core and sent
off to the consumer. The consumer can formally verify the approximation quality
of the IP core at a fraction of the typical computational cost for formal verification.
In this paper, we first make the case for proof-carrying approximate circuits
and then demonstrate the feasibility of the approach by a set of synthesis experiments
using an exemplary approximation framework.'

text: "On the circuit level, the design paradigm Approximate Computing seeks to
trade off computational accuracy against a target metric, e.g., energy consumption.
This trade-off is possible for many applications due to their inherent resiliency
against inaccuracies.\r\nIn the past, several automated approximation frameworks
have been presented, which either utilize designated approximation techniques
or libraries to replace approximable circuit parts with inaccurate versions. The
frameworks invoke a search algorithm to iteratively explore the search space of
performance degraded circuits, and validate their quality individually. \r\nIn
this paper, we propose to reverse this procedure. Rather than exploring the search
space, we delineate the approximate parts of the search space which are guaranteed
to lead to valid approximate circuits. Our methodology is supported by formal
verification and independent of approximation techniques. Eventually, the user
is provided with quality bounds of the individual approximable circuit parts.
Consequently, our approach guarantees that any approximate circuit which implements
these parts within the determined quality constraints satisfies the global quality
constraints, superseding a subsequent quality verification.\r\nIn our experimental
results, we present the runtimes of our approach."

text: Radiation tolerance in FPGAs is an important field of research particularly
for reliable computation in electronics used in aerospace and satellite missions.
The motivation behind this research is the degradation of reliability in FPGA
hardware due to single-event effects caused by radiation particles. Redundancy
is a commonly used technique to enhance the fault-tolerance capability of radiation-sensitive
applications. However, redundancy comes with an overhead in terms of excessive
area consumption, latency, and power dissipation. Moreover, the redundant circuit
implementations vary in structure and resource usage with the redundancy insertion
algorithms as well as number of used redundant stages. The radiation environment
varies during the operation time span of the mission depending on the orbit and
space weather conditions. Therefore, the overheads due to redundancy should also
be optimized at run-time with respect to the current radiation level. In this
paper, we propose a technique called Dynamic Reliability Management (DRM) that
utilizes the radiation data, interprets it, selects a suitable redundancy level,
and performs the run-time reconfiguration, thus varying the reliability levels
of the target computation modules. DRM is composed of two parts. The design-time
tool flow of DRM generates a library of various redundant implementations of the
circuit with different magnitudes of performance factors. The run-time tool flow,
while utilizing the radiation/error-rate data, selects a required redundancy level
and reconfigures the computation module with the corresponding redundant implementation.
Both parts of DRM have been verified by experimentation on various benchmarks.
The most significant finding we have from this experimentation is that the performance
can be scaled multiple times by using partial reconfiguration feature of DRM,
e.g., 7.7 and 3.7 times better performance results obtained for our data sorter
and matrix multiplier case studies compared with static reliability management
techniques. Therefore, DRM allows for maintaining a suitable trade-off between
computation reliability and performance overhead during run-time of an application.

text: 'Automated synthesis of approximate circuits via functional approximations
is of prominent importance to provide efficiency in energy, runtime, and chip
area required to execute an application. Approximate circuits are usually obtained
either through analytical approximation methods leveraging approximate transformations
such as bit-width scaling or via iterative search-based optimization methods when
a library of approximate components, e.g., approximate adders and multipliers,
is available. For the latter, exploring the extremely large design space is challenging
in terms of both computations and quality of results. While the combination of
both methods can create more room for further approximations, the \textit{Design
Space Exploration}~(DSE) becomes a crucial issue. In this paper, we present such
a hybrid synthesis methodology that applies a low-cost analytical method followed
by parallel stochastic search-based optimization. We address the DSE challenge
through efficient pruning of the design space and skipping unnecessary expensive
testing and/or verification steps. The experimental results reveal up to 10.57x
area savings in comparison with both purely analytical or search-based approaches. '

text: "Modern machine learning (ML) techniques continue to move into the embedded
system space because traditional centralized compute resources do not suit certain
application domains, for example in mobile or real-time environments. Google’s
TensorFlow Lite (TFLite) framework supports this shift from cloud to edge computing
and makes ML inference accessible on resource-constrained devices. While it offers
the possibility to partially delegate computation to hardware accelerators, there
is no such “delegate” available to utilize the promising characteristics of reconfigurable
hardware.\r\nThis thesis incorporates modern platform FPGAs into TFLite by implementing
a modular delegate framework, which allows accelerators within the programmable
logic to take over the execution of neural network layers. To facilitate the necessary
hardware/software codesign, the FPGA delegate is based on the operating system
for reconfigurable\r\ncomputing (ReconOS), whose partial reconfiguration support
enables the instantiation of model-tailored accelerator architectures. In the
hardware back-end, a streaming-based prototype accelerator for the MobileNet model
family showcases the working order of the platform, but falls short of the desired
performance. Thus, it indicates the need for further exploration of alternative
accelerator designs, which the delegate could automatically synthesize to meet
a model’s demands."

text: Existing approaches and tools for the generation of approximate circuits often
lack generality and are restricted to certain circuit types, approximation techniques,
and quality assurance methods. Moreover, only few tools are publicly available.
This hinders the development and evaluation of new techniques for approximating
circuits and their comparison to previous approaches. In this paper, we first analyze
and classify related approaches and then present CIRCA, our flexible framework
for search-based approximate circuit generation. CIRCA is developed with a focus
on modularity and extensibility. We present the architecture of CIRCA with its
clear separation into stages and functional blocks, report on the current prototype,
and show initial experiments.

text: State-of-the-art frameworks for generating approximate circuits usually rely
on information gained through circuit synthesis and/or verification to explore
the search space and to find an optimal solution. Throughout the process, a large
number of circuits may be subject to processing, leading to considerable runtimes.
In this work, we propose a search which takes error bounds and pre-computed impact
factors into account to reduce the number of invoked synthesis and verification
processes. In our experimental results, we achieved speed-ups of up to 76x while
area savings remain comparable to the reference search method, simulated annealing.

text: "State-of-the-art frameworks for generating approximate circuits automatically
explore the search space in an iterative process - often greedily. Synthesis and
verification processes are invoked in each iteration to evaluate the found solutions
and to guide the search algorithm. As a result, a large number of approximate
circuits is subjected to analysis - leading to long runtimes - but only a few
approximate circuits might form an acceptable solution.\r\n\r\nIn this paper,
we present our Jump Search (JS) method which seeks to reduce the runtime of an
approximation process by reducing the number of expensive synthesis and verification
steps. To reduce the runtime, JS computes impact factors for each approximation
candidate in the circuit to create a selection of approximate circuits without
invoking synthesis or verification processes. We denote the selection as path
from which JS determines the final solution. In our experimental results, JS achieved
speed-ups of up to 57x while area savings remain comparable to the reference search
method, Simulated Annealing."

text: Advances in electromyographic (EMG) sensor technology and machine learning
algorithms have led to an increased research effort into high density EMG-based
pattern recognition methods for prosthesis control. With the goal set on an autonomous
multi-movement prosthesis capable of performing training and classification of
an amputee’s EMG signals, the focus of this paper lies in the acceleration of
the embedded signal processing chain. We present two Xilinx Zynq-based architectures
for accelerating two inherently different high density EMG-based control algorithms.
The first hardware accelerated design achieves speed-ups of up to 4.8 over the
software-only solution, allowing for a processing delay lower than the sample
period of 1 ms. The second system achieved a speed-up of 5.5 over the software-only
version and operates at a still satisfactory low processing delay of up to 15
ms while providing a higher reliability and robustness against electrode shift
and noisy channels.

text: Modern Boolean satisfiability solvers can emit proofs of unsatisfiability.
There is substantial interest in being able to verify such proofs and also in
using them for further computations. In this paper, we present an FPGA accelerator
for checking resolution proofs, a popular proof format. Our accelerator exploits
parallelism at the low level by implementing the basic resolution step in hardware,
and at the high level by instantiating a number of parallel modules for proof
checking. Since proof checking involves highly irregular memory accesses, we employ
Hybrid Memory Cube technology for accelerator memory. The results show that while
the accelerator is scalable and achieves speedups for all benchmark proofs, performance
improvements are currently limited by the overhead of transitioning the proof
into the accelerator memory.
