%\usepackage{cite}
107
% cite.sty was written by Donald Arseneau
108
% V1.6 and later of IEEEtran pre-defines the format of the cite.sty package
109
% \cite{} output to follow that of IEEE. Loading the cite package will
110
% result in citation numbers being automatically sorted and properly
111
% "compressed/ranged". e.g., [1], [9], [2], [7], [5], [6] without using
112
% cite.sty will become [1], [2], [5]--[7], [9] using cite.sty. cite.sty's
113
% \cite will automatically add leading space, if needed. Use cite.sty's
114
% noadjust option (cite.sty V3.8 and later) if you want to turn this off.
115
% cite.sty is already installed on most LaTeX systems. Be sure and use
116
% version 4.0 (2003-05-27) and later if using hyperref.sty. cite.sty does
117
% not currently provide for hyperlinked citations.
118
% The latest version can be obtained at:
119
% http://www.ctan.org/tex-archive/macros/latex/contrib/cite/

% *** MATH PACKAGES ***
172
%
173
%\usepackage[cmex10]{amsmath}
174
% A popular package from the American Mathematical Society that provides
175
% many useful and powerful commands for dealing with mathematics. If using
176
% it, be sure to load this package with the cmex10 option to ensure that
177
% only type 1 fonts will utilized at all point sizes. Without this option,
178
% it is possible that some math symbols, particularly those within
179
% footnotes, will be rendered in bitmap form which will result in a
180
% document that can not be IEEE Xplore compliant!
181
%
182
% Also, note that the amsmath package sets \interdisplaylinepenalty to 10000
183
% thus preventing page breaks from occurring within multiline equations. Use:
184
%\interdisplaylinepenalty=2500
185
% after loading amsmath to restore such page breaks as IEEEtran.cls normally
186
% does. amsmath.sty is already installed on most LaTeX systems. The latest
187
% version and documentation can be obtained at:

196
%\usepackage{algorithmic}
197
% algorithmic.sty was written by Peter Williams and Rogerio Brito.
198
% This package provides an algorithmic environment fo describing algorithms.
199
% You can use the algorithmic environment in-text or within a figure
200
% environment to provide for a floating algorithm. Do NOT use the algorithm
201
% floating environment provided by algorithm.sty (by the same authors) or
202
% algorithm2e.sty (by Christophe Fiorio) as IEEE does not use dedicated
203
% algorithm float types and packages that provide these will not provide
204
% correct IEEE style captions. The latest version and documentation of
205
% algorithmic.sty can be obtained at:
206
% http://www.ctan.org/tex-archive/macros/latex/contrib/algorithms/
207
% There is also a support site at:
208
% http://algorithms.berlios.de/index.html
209
% Also of interest may be the (relatively newer and more customizable)
210
% algorithmicx.sty package by Szasz Janos:

217
%
218
%\usepackage{array}
219
% Frank Mittelbach's and David Carlisle's array.sty patches and improves
220
% the standard LaTeX2e array and tabular environments to provide better
221
% appearance and additional user controls. As the default LaTeX2e table
222
% generation code is lacking to the point of almost being broken with
223
% respect to the quality of the end results, all users are strongly
224
% advised to use an enhanced (at the very least that provided by array.sty)
225
% set of table tools. array.sty is already installed on most systems. The
226
% latest version and documentation can be obtained at:
227
% http://www.ctan.org/tex-archive/macros/latex/required/tools/
228
 
229
 
230
%\usepackage{mdwmath}
231
%\usepackage{mdwtab}
232
% Also highly recommended is Mark Wooding's extremely powerful MDW tools,
233
% especially mdwmath.sty and mdwtab.sty which are used to format equations
234
% and tables, respectively. The MDWtools set is already installed on most
235

% *** SUBFIGURE PACKAGES ***
255
%\usepackage[tight,footnotesize]{subfigure}
256
% subfigure.sty was written by Steven Douglas Cochran. This package makes it
257
% easy to put subfigures in your figures. e.g., "Figure 1a and 1b". For IEEE
258
% work, it is a good idea to load it with the tight package option to reduce
259
% the amount of white space around the subfigures. subfigure.sty is already
260
% installed on most LaTeX systems. The latest version and documentation can
261
% be obtained at:
262
% http://www.ctan.org/tex-archive/obsolete/macros/latex/contrib/subfigure/
263
% subfigure.sty has been superceeded by subfig.sty.

265
 
266
 
267
%\usepackage[caption=false]{caption}
268 159 guanucolui
\usepackage[font=footnotesize,caption=false]{subfig}
269 153 guanucolui
% subfig.sty, also written by Steven Douglas Cochran, is the modern
270
% replacement for subfigure.sty. However, subfig.sty requires and
271
% automatically loads Axel Sommerfeldt's caption.sty which will override
272
% IEEEtran.cls handling of captions and this will result in nonIEEE style
273
% figure/table captions. To prevent this problem, be sure and preload
274
% caption.sty with its "caption=false" package option. This is will preserve
275
% IEEEtran.cls handing of captions. Version 1.3 (2005/06/28) and later
276
% (recommended due to many improvements over 1.2) of subfig.sty supports
277
% the caption=false option directly:
278
%\usepackage[caption=false,font=footnotesize]{subfig}

% The latest version and documentation can be obtained at:

288
% *** FLOAT PACKAGES ***
289
%
290
%\usepackage{fixltx2e}
291
% fixltx2e, the successor to the earlier fix2col.sty, was written by
292
% Frank Mittelbach and David Carlisle. This package corrects a few problems
293
% in the LaTeX2e kernel, the most notable of which is that in current
294
% LaTeX2e releases, the ordering of single and double column floats is not
295
% guaranteed to be preserved. Thus, an unpatched LaTeX2e can allow a
296
% single column figure to be placed prior to an earlier double column
297
% figure. The latest version and documentation can be found at:
298
% http://www.ctan.org/tex-archive/macros/latex/base/
299
 
300
 
301
 
302
%\usepackage{stfloats}
303
% stfloats.sty was written by Sigitas Tolusis. This package gives LaTeX2e
304
% the ability to do double column floats at the bottom of the page as well
305
% as the top. (e.g., "\begin{figure*}[!b]" is not normally possible in
306
% LaTeX2e). It also provides a command:
307
%\fnbelowfloat
308
% to enable the placement of footnotes below bottom floats (the standard
309
% LaTeX2e kernel puts them above bottom floats). This is an invasive package
310
% which rewrites many portions of the LaTeX2e float routines. It may not work
311
% with other packages that modify the LaTeX2e float routines. The latest
312
% version and documentation can be obtained at:
313
% http://www.ctan.org/tex-archive/macros/latex/contrib/sttools/
314
% Documentation is contained in the stfloats.sty comments as well as in the
315
% presfull.pdf file. Do not use the stfloats baselinefloat ability as IEEE
316
% does not allow \baselineskip to stretch. Authors submitting work to the
317
% IEEE should note that IEEE rarely uses double column equations and
318
% that authors should try to avoid such use. Do not be tempted to use the
319
% cuted.sty or midfloat.sty packages (also by Sigitas Tolusis) as IEEE does
320
% not format its papers in such ways.

% IEEEtran.cls defaults to using nonbold math in the Abstract.
449
% This preserves the distinction between vectors and scalars. However,
450
% if the conference you are submitting to favors bold math in the abstract,
451
% then you can use LaTeX's standard command \boldmath at the very start
452
% of the abstract to achieve this. Many IEEE journals/conferences frown on
453
% math in the abstract anyway.

En estas últimas décadas los sistemas embebidos han cobrado una gran importancia, en particular se hace referencia a los Dispositivos Lógicos Programables (PLDs, siglas en inglés). Estos dispositivos lógicos actualmente ofrecen grandes recursos de hardware debido a los avances en los procesos de integración en su fabricación, obviamente que ha beneficiado a todos los circuitos integrados (ICs, siglas en inglés) en general.
473
 
474
Los Dispositivos Lógicos Programables fueron introducidos a medidos de 1970s. Se basaba en la idea de construir circuitos lógicos combinacionales que fueran programables. Contrariamente a los microprocesadores, los cuales pueden correr un programa sobre un hardware fijo, la programabilidad de los PLDs hace referencia a niveles de hardware. En otras palabras, un PLD es un chip de propósitos generales cuyo hardware puede ser reconfigurado dependiendo de especificaciones particulares del desarrollador.
475
 
476
Si bien las diferentes industrias (militar[REF], automotriz[REF], comunicaciones[REF], de consumo[REF], etc.) son quienes demandan constantemente avances tecnológicos, muchas veces el sector académico resulta ser el gestor de grandes desarrollos e investigaciones que beneficia a estas industrias. En nuestra región la tecnología PLDs se encuentra en su auge hace unos años. Instituciones gubernamentales de defensa[REF], aeroespaciales[REF], comunicaciones[REF] están implementando dispositivos como FPGAs y CPLDs en sus diseños. Además existe una constante actualización por parte de las instituciones académicas en los programas analíticos de las carreras relacionadas a los sistemas embebidos[REF].
477
 
478
En el estudio de nuevos sistemas digitales las herramientas de software son eficientes, pues permiten realizar simulaciones que se asemejan a la implementación física. Pero muchas veces son necesarias las implementaciones en hardware y es ahí donde se hacen necesarias las plataformas evaluadoras. Estas placas disponen de un diseño que cubre un gran espectro de aplicación según la tecnología y la complejidad del desarrollo. Este concepto no solo se aplica a los sistemas embebidos, pues varias áreas científicas requieren de un gran porcentaje de laboratorio[REF].
479
 
480
La mayoría de las plataformas de evaluación comerciales son fabricadas en el exterior del país. Se han encontrado desarrollos nacionales pero no son comercializados sino usados en laboratorios universitarios. Entre las empresas fabricantes de sistemas embebidos basados en dispositivos PLDs, se destacan: Xilix, Altera y Digilent. Los principales perfiles de sus desarrollos se encuentran orientados a,
481
\begin{itemize}
482
\item Sistemas de comunicaciones
483
\item Procesamiento de Señales Digitales (DSP)
484
\item Automovilismo
485
\end{itemize}
486
En la Figura [REF] se pueden ver tres diferentes plataformas orientadas al diseño de sistemas digitales \footnote{Alguna de estas plataformas disponen de módulos conversores ADC y DAC, por lo que se podría decir que también permiten la implementación de sistemas analógicos en dominio discreto.}.

% Note that \label must occur AFTER (or within) \caption.
551
% For figures, \caption should occur after the \includegraphics.
552
% Note that IEEEtran v1.7 and later has special internal code that
553
% is designed to preserve the operation of \label within \caption
554
% even when the captionsoff option is in effect. However, because
555
% of issues like this, it may be the safest practice to put all your
556
% \label just after \caption rather than within \caption{}.
557
%
558
% Reminder: the "draftcls" or "draftclsnofoot", not "draft", class
559
