 Torc
is an open-source C++ infrastructure and tool set for
reconfigurable computing, released under the GNU GPL
3.0 license. It is suitable for custom
research applications, for CAD tool development, and for
architecture exploration.
Researchers are often
sidetracked from their work by tool and infrastructure
needs, and much existing research therefore builds upon
simplified device models, or provides only limited support
for commercial netlist formats.
The Torc infrastructure can
read, write, and manipulate EDIF and XDL netlists, as well
as Xilinx bitstream packets (but not configuration frame
internals). Torc also provides exhaustive wiring and
logic information for all major Xilinx devices, derived
from non-proprietary sources. Similar support for
Altera architectures and designs could be provided if the
necessary data were available. Torc also supports
any custom research architecture that can be described in
XDLRC.
Currently supported devices
include all Virtex, VirtexE, Virtex2, Virtex2 Pro,
Virtex4, Virtex5, Virtex6, Virtex6L, Spartan3E, Spartan6,
and Spartan6L devices.
Torc consists of compilable C++
code, but provides no downloadable executables. The
user is responsible for using the provided functionality
to build their own executables for the target system, very
possibly an embedded system.
Documentation exists primarily
in the form of example code, unit test code, and Doxygen
documentation.
