[Overview]
The mapping tool, named NoCmap, is a concise C++ program which automatically maps a
given set of IPs onto a generic regular NoC architecture such that the total communication
energy is minimized. At the same time, the performance of the resulting communication system
is guaranteed to satisfy the specified design constraints through bandwidth reservation.
[Features and Highlights]
NoCmap also uses Ebit energy model.
It accepts two possible formats for describing the to-be-mapped application.
The first format is the APCG format, which is accepted by nocmap in
combination with ``-apcg'' switch. In this format, each line
in the input APCG file contains a 4-tuple, which specifies the source
IP, the destination IP, the communication volume and the communication
bandwidth requirement, respectively. The second supported format is
the ``traffic-config'' format, which is accepted by nocmap when
switch ``-traffic_config'' is enabled. In this case, each
line in the input file contains a 3-tuple, which specifies the source
IP, the destination IP and the packet rate from the source to the
destination. When executed, \emph{nocmap} linearly scale this packet
rate to generate the communication volume and the bandwidth
requirement between these two IPs.
[Download and Install]
Download release 1.2
NoCmap was developed and tested mainly in GNU/Linux. To install, download the
tgz file and use the command "tar xvzf nocmap.1.2.tgz" to extract the files.
Just run "make" in nocmap/src directory and the executable named "nocmap"
will be compiled. Copy or link this binary to a directory in your search path
if you like.
Running "nocmap -h" will print a brief description of switches available.
At the same time, please refer to the README.txt file included in the release
for more detailed usage and explanation of the tool.
Some simple examples are also provided with the release which can be checked out
under "examples" directory.
