text: 'Mapping applications that consist of a collection of cores to FPGA accelerators
and optimizing their performance is a challenging task in high performance reconfigurable
computing. We present IMORC, an architectural template and highly versatile on-chip
interconnect. IMORC links provide asynchronous FIFOs and bitwidth conversion which
allows for flexibly composing accelerators from cores running at full speed within
their own clock domains, thus facilitating the re-use of cores and portability.
Further, IMORC inserts performance counters for monitoring runtime data. In this
paper, we first introduce the IMORC architectural template and the on-chip interconnect,
and then demonstrate IMORC on the example of accelerating the k-th nearest neighbor
thinning problem on an XD1000 reconfigurable computing system. Using IMORC''s
monitoring infrastructure, we gain insights into the data-dependent behavior of
the application which, in turn, allow for optimizing the accelerator. '

text: 'In this work we present EvoCache, a novel approach for implementing application-specific
caches. The key innovation of EvoCache is to make the function that maps memory
addresses from the CPU address space to cache indices programmable. We support
arbitrary Boolean mapping functions that are implemented within a small reconfigurable
logic fabric. For finding suitable cache mapping functions we rely on techniques
from the evolvable hardware domain and utilize an evolutionary optimization procedure.
We evaluate the use of EvoCache in an embedded processor for two specific applications
(JPEG and BZIP2 compression) with respect to execution time, cache miss rate and
energy consumption. We show that the evolvable hardware approach for optimizing
the cache functions not only significantly improves the cache performance for
the training data used during optimization, but that the evolved mapping functions
generalize very well. Compared to a conventional cache architecture, EvoCache
applied to test data achieves a reduction in execution time of up to 14.31% for
JPEG (10.98% for BZIP2), and in energy consumption by 16.43% for JPEG (10.70%
for BZIP2). We also discuss the integration of EvoCache into the operating system
and show that the area and delay overheads introduced by EvoCache are acceptable. '

text: 'In this paper, we introduce the Woolcano reconfigurable processor architecture.
The architecture is based on the Xilinx Virtex-4 FX FPGA and leverages the Auxiliary
Processing Unit (APU) as well as the partial reconfiguration capabilities to provide
dynamically reconfigurable custom instructions. We also present a hardware tool
flow that automatically translates software functions into custom instructions
and a software tool flow that creates binaries using these instructions. While
previous research on processors with reconfigurable functional units has been
performed predominantly with simulation, the Woolcano architecture allows for
exploring dynamic instruction set extension with commercially available hardware.
Finally, we present a case study demonstrating a custom floating-point instruction
generated with our approach, which achieves a 40x speedup over software-emulated
floating-point operations and a 21% speedup over the Xilinx hardware floating-point
unit. '

text: ' In this thesis, we propose to use a reconfigurable processor as main computation
element in embedded systems for applications from the multi-media and communications
domain. A reconfigurable processor integrates an embedded CPU core with a Reconfigurable
Processing Unit (RPU). Many of our target applications require real-time signal-processing
of data streams and expose a high computational demand. The key challenge in designing
embedded systems for these applications is to find an implementation that satisfies
the performance goals and is adaptable to new applications, while the system cost
is minimized. Implementations that solely use an embedded CPU are likely to miss
the performance goals. Application-Specific Integrated Circuit (ASIC)-based coprocessors
can be used for some high-volume products with fixed functions, but fall short
for systems with varying applications. We argue that a reconfigurable processor
with a coarse-grained, dynamically reconfigurable array of modest size provides
an attractive implementation platform for our application domain. The computational
intensive application kernels are executed on the RPU, while the remaining parts
of the application are executed on the CPU. Reconfigurable hardware allows for
implementing application specific coprocessors with a high performance, while
the function of the coprocessor can still be adapted due to the programmability.
So far, reconfigurable technology is used in embedded systems primarily with static
configurations, e.g., for implementing glue-logic, replacing ASICs, and for implementing
fixed-function coprocessors. Changing the configuration at runtime enables a number
of interesting application modes, e.g., on-demand loading of coprocessors and
time-multiplexed execution of coprocessors, which is commonly denoted as hardware
virtualization. While the use of static configurations is well understood and
supported by design-tools, the role of dynamic reconfiguration is not well investigated
yet. Current application specification methods and design-tools do not provide
an end-to-end tool-flow that considers dynamic reconfiguration. A key idea of
our approach is to reduce system cost by keeping the size of the reconfigurable
array small and to use hardware virtualization techniques to compensate for the
limited hardware resources. The main contribution of this thesis is the codesign
of a reconfigurable processor architecture named ZIPPY, the corresponding hardware
and software implementation tools, and an application specification model which
explicitly considers hardware virtualization. The ZIPPY architecture is widely
parametrized and allows for specifying a whole family of processor architectures.
The implementation tools are also parametrized and can target any architectural
variant. We evaluate the performance of the architecture with a system-level,
cycle-accurate cosimulation framework. This framework enables us to perform design-space
exploration for a variety of reconfigurable processor architectures. With two
case studies, we demonstrate, that hardware virtualization on the Zippy architecture
is feasible and enables us to trade-off performance for area in embedded systems.
Finally, we present a novel method for optimal temporal partitioning of sequential
circuits, which is an important form of hardware virtualization. The method based
on Slowdown and Retiming allows us to decompose any sequential circuit into a
number of smaller, communicating subcircuits that can be executed on a dynamically
reconfigurable architecture. '

text: ' This paper presents a novel method for optimal temporal partitioning of
sequential circuits for time-multiplexed reconfigurable architectures. The method
bases on slowdown and retiming and maximizes the circuit''s performance during
execution while restricting the size of the partitions to respect the resource
constraints of the reconfigurable architecture. We provide a mixed integer linear
program (MILP) formulation of the problem, which can be solved exactly. In contrast
to related work, our approach optimizes performance directly, takes structural
modifications of the circuit into account, and is extensible. We present the application

text: ' Reconfigurable architectures that tightly integrate a standard CPU core
with a field-programmable hardware structure have recently been receiving impact
of these design decisions on the overall system performance is a challenging task.
In this paper, we first present a framework for the cycle-accurate performance
evaluation of hybrid reconfigurable processors on the system level. Then, we discuss
a reconfigurable processor for data-streaming applications, which attaches a coarse-grained
reconfigurable unit to the coprocessor interface of a standard embedded CPU core.
By means of a case study we evaluate the system-level impact of certain design
features for the reconfigurable unit, such as multiple contexts, register replication,
and hardware context scheduling. The results illustrate that a system-level evaluation
framework is of paramount importance for studying the architectural trade-offs
and optimizing design parameters for reconfigurable processors.'

text: ' This paper presents TKDM, a PC-based high-performance reconfigurable computing
environment. The TKDM hardware consists of an FPGA module that uses the DIMM (dual
inline memory module) bus for high-bandwidth and low-latency communication with
the host CPU. The system''s firmware is integrated with the Linux host operating
system and offers functions for data communication and FPGA reconfiguration. The
intended use of TKDM is that of a dynamically reconfigurable co-processor for
data streaming applications. The system''s firmware can be customized for specific
application domains to facilitate simple and easy-to-use programming interfaces. '

text: 'Wearable computers are embedded into the mobile environment of their users.
A design challenge for wearable systems is to combine the high performance required
for tasks such as video decoding with the low energy consumption required to maximise
battery runtimes and the flexibility demanded by the dynamics of the environment
and the applications. In this paper, we demonstrate that reconfigurable hardware
technology is able to answer this challenge. We present the concept and the prototype
implementation of an autonomous wearable unit with reconfigurable modules (WURM).
We discuss experiments that show the uses of reconfigurable hardware in WURM:
ASICs-on-demand and adaptive interfaces. Finally, we present an experiment with
an operating system layer for WURM.'

text: ' This paper presents the acceleration of minimum-cost covering problems by
instance-specific hardware. First, we formulate the minimum-cost covering problem
and discuss a branch \& bound algorithm to solve it. Then we describe instance-specific
hardware architectures that implement branch \& bound in 3-valued logic and use
reduction techniques similar to those found in software solvers. We further present
prototypical accelerator implementations and a corresponding design tool flow.
Our experiments reveal significant raw speedups up to five orders of magnitude
for a set of smaller unate covering problems. Provided that hardware compilation
times can be reduced, we conclude that instance-specific acceleration of hard
minimum-cost covering problems will lead to substantial overall speedups. '
