38: %\emph{Informal description of the purpose of the PP (3-5 lines)}
39: Every embedded system consists of software which is written in a high
40: level language, compiled to machine language and executed on a
41: processor. For robust embedded systems new verified compilation,
42: simulation and specification methods are necessary to optimize for
43: performance, power, space, concurrency and reliability.

48: %Compilation Techniques for Reliability
49:
50: Because of the exponential increase of the number of transistors and
51: the continuing decrease of the feature sizes of current processors
52: soft errors mainly caused by energetic particles are becoming an
53: important design issue for robust embedded systems. Blome et
54: al.~\cite{Blome+06} observed that a majority of faults that affect the
55: architectural state of a processor come from the register file. Lee
56: and Shrivastava and proposed different solutions to cope with this
57: problem. The first assigns variables depending on their lifetime to
58: either the ECC protected or the unprotected part of a register file to
59: balance energy consumption and reliability \cite{LeeShrivastava09a}.
60: The second spills registers to ECC protected memory if the register
61: contents are not used for a long period \cite{LeeShrivastava09c}.
62: There exist complete software solutions which use different forms of
63: code duplications \cite{Oh+02a,Reis+05}, which do failure
64: virtualization \cite{WapplerMueller08} or which use techniques like
65: control flow checking \cite{Oh+02b}. A complete overview of processor
66: description languages and generation of compilers and simulators from
67: processors specifications gives the book of Mishra and Dutt \cite{MishraDutt08}.
68: A good survey of current instruction set simulators gives our chapter
69: in the Handbook of Signal Processing systems \cite{BrHoKr09}. A famous
70: instruction set simulator with modelling of energy consumtion is Wattch
71: \cite{BrooksTiwariMartonosi00}.

78: %\emph{Brief description of your own contributions to the related
79: %scientific state-of-the art (5-10 lines)}
80: Jens Knoop has a long history on work on program analysis with topics
81: like partial redundancy elimination or lazy code motion
82: \cite{knoop:DSP:2008:1575,conf/cc/XueK06,scholz04}. Recently he
83: changed his research focus on worst case execution time analysis
84: \cite{SchrSchoKn09,Prantl:WLPE2008,prantl_et_al:DSP:2008:1661,
85: kirner_et_al:DSP:2008:1657,kirner_et_al:DSP:2007:1197}. He is involved
86: in the organization of many compiler conferences and since 2002 program
87: cochair of the yearly workshop on compiler optimization meets verification.
88:
89: Andreas Krall does research in the area of architecture description
90: languages and the automatic generation of highly optimizing compilers,
91: efficient instruction set simulators and hardware from one single
92: specification of a processor \cite{BrFeKrRi09,BrEbKr07,FaKrHo07,
93: FarKrStBrand06,Krall+04micro}. An important focus is on optimization
94: techniques for embedded processors
95: \cite{EbBrSchKrWiKa08,MeKr07,PrKrHo06,HiKr03} as he lead the Christian
96: Doppler research laboratory {\em compilation techniques for embedded
97: processors} with partners from industry (Infineon, OnDemand
98: Microelectronics).
