<h2>1. Central Processing Unit</h2>
<p>
The CPU is the hardware within a computer system which executes computer instructions by performing arithmetic,
logic, and I/O operations. With our CPU virtualization technology, multiple VM can share one physical CPU to
improve utilization rate. With multi-core virtualization technology, one VM can have multi-core virtual CPU.

you complete control of your computing resources in our secured datacenter.</p>
<p>CloudCom's technology in CPU, GPU, and memory help you quickly rent, boot, and scale up or down your VM based on
your computing requirements</p>
<p>The economics of computing is evoled to model of pay-as-you-go. CloudCom only charge you based on how much you use
our service hour by hour.</p>
<p>With new API for developers, more developers use CloudCom's services to host website and distribute applications to
customers.</p>

// It's possible to read the response frame in a series of read operations, provided
// each read operation is preceded by SPI_DATAREAD byte from the host.
// Unfortunately, the PN532 sends first byte of the second and successive response chunks

// and then begin full-featured read operation
// The PN532 does not shift the internal register on the receive operation, which allows us to read the whole response

// CS ..._/---\___________________________/---\________/------\_____________/-----\_________/---\____________/---...
// MOSI (host=>pn532) ... 0x03 0x00 0x00 0x00 0x00 0x00 0x03 0x00 0x00 0x03 0x00

* @note For example if you send the SELECT_ALL (0x93, 0x20) = [ 10010011,

* 0x00) to define the correct odd parity bits. This is only an example to

* the frame (data, CRC and parity) is completely done by libnfc. This can be
* very useful for testing purposes. Some protocols (e.g. MIFARE Classic)

# - Run Doxygen
#
# Adds a doxygen target that runs doxygen to generate the html
# and optionally the LaTeX API documentation.
# The doxygen target is added to the doc target as dependency.
# i.e.: the API documentation is built with:
# make doc
#
# USAGE: GLOBAL INSTALL
#
# Install it with:
# cmake ./ && sudo make install
# Add the following to the CMakeLists.txt of your project:
# include(UseDoxygen OPTIONAL)
# Optionally copy Doxyfile.in in the directory of CMakeLists.txt and edit it.
#
# USAGE: INCLUDE IN PROJECT
#
# set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})
# include(UseDoxygen)
# Add the Doxyfile.in and UseDoxygen.cmake files to the projects source directory.
#
#
# Variables you may define are:
# DOXYFILE_OUTPUT_DIR - Path where the Doxygen output is stored. Defaults to "doc".
#
# DOXYFILE_LATEX_DIR - Directory where the Doxygen LaTeX output is stored. Defaults to "latex".
#
# DOXYFILE_HTML_DIR - Directory where the Doxygen html output is stored. Defaults to "html".
