C/C++ interpreter Ch 5.5, and Embedded Ch 5.5 Released
DAVIS, California, October 16, 2005 -
SoftIntegration, Inc. today announced the availability of Ch 5.5 and Embedded Ch 5.5. Ch is an embeddable C/C++ interpreter for cross-platform scripting,
2D/3D plotting, numerical computing, shell programming and embedded scripting.
Ch and Embedded Ch version 5.5 are the most stable release.
The new release mainly added Embedded Ch function callback features,
more C99 features, and powerful
new plotting capabilities,
Ch Professional Edition
smooth surface mesh for 3D plotting.
The view angle of 3D plots can be changed
and coordinates of 2D plots can be tracked by a mouse.
Ch Professional Edition
is now supported in QNX. This release also fixed many reported bugs.
"Ch is an excellent environment for research and teaching.
I use it for research and teaching on mechatronics and control,"
said Professor David Auslander at
the University of California at Berkeley.
"To me the main advantage of an interpreter is portability.
Ch allows C programs to be executed portably across different platforms.
a major advantage of Ch is its user-friendly
mathematical and graphical
infrastructure. Getting that in C, C++ or Java requires assembling a
large collection of libraries from a variety of sources, each with its own
quirks. I am very impressed with the
salient graphical plotting capabilities in Ch version 5.5.
They are easy to use and
very useful for applications in engineering and science."
"We greatly appreciate the power and flexibility of a C interpreter bring to the simulation and design of power electronics and motor drive systems,"
added Hua Jin, president of Powersim Inc.
"PSIM from Powersim Inc.
is specifically developed for
simulation and design of power electronics and
motor drive systems.
An embedded C interpreter makes it extremely easy to write C code in PSIM without the need of a separate C compiler. The response from our customers on the C Script Block in PSIM, powered by the Embedded Ch interpreter, is very good. Thank you for a well-developed product."

Below is a list of Ch major features.
Ch supports 1999 ISO C Standard (C99) and C++ classes. Ch also supports
many industry standards with over 8,000 functions, including POSIX,
socket/Winsock, X11/Motif, OpenGL, ODBC, C LAPACK, GTK+, Win32, XML, and
CGI. With built-in
functions in static or dynamic binary C/C++ libraries can be executed
in Ch script file or Ch command shell without re-compilation.
Programs can also be developed and executed using a number of
user-friendly Integrated Development Environment (IDE) such as
Ch is easy and simple for embedded scripting.
Embedded Ch allows users to embed Ch into C/C++ application programs
and hardware as a scripting engine.
It is ideal for open-architecture application integration.
With Embedded Ch, C/C++ applications can be extended with all features of Ch.
It allows execution of C/C++ scripts generated dynamically.
Embedded Ch supports multi-threading and has a small footprint.
The pointer and time deterministic
nature of the C language provides a perfect interface with hardware in real-time systems.
Shell programming and cross-platform scripting
Ch shell is C compatible shell while C-shell (csh) is a C like shell. Ch is an interpretive implementation of C, similar to Unix/MS-DOS shells. Ch in Windows includes over 200 commonly used Unix commands for portable shell programming. Ch can also be used as a login shell just like sh, csh and ksh. Ch bridges the gap between the C language and shell languages. With its built-in string type and many enhanced scripting features, Ch is an alternative to other scripting languages for automating repetitive tasks, regression test, and hardware testing with direct interface to hardware.
Ch graphical extensions are the best choice for plotting in
the C/C++ domain.
Ch supports high-level 2D/3D graphical plotting.
Two and three dimensional graphical plots can be very easily accomplished.
Plots in Ch can be generated from data arrays or files, and can be displayed on a screen, saved as an image file in a variety of ifferent file formats, or output to the stdout stream in a proper image format for display in a Web browser through a Web server.
With SoftIntegration graphical library (SIGL), the same
program using 2D/3D plotting features can be executed in Ch
or compiled using C++ compilers without any modification.
Ch numerical extensions are the best choice for numerical computing in
the C/C++ domain.
Ch has built-in generic mathematical
functions and computational arrays for linear algebra and matrix
It contains advanced high-level numerical functions
for linear systems, differential equation solving, integration,
non-linear equations, Fourier analysis, curve fitting, etc. For
example, linear system equation b = A*x can be written verbatim in Ch.
Ch supports C LAPACK,
GNU Multiple Precision Arithmetic Library, and
GNU Scientific Library.
Applications written using these libraries
can be executed in Ch
or compiled using C compilers without any modification.
Ch toolkits and third party software support
Ch is ideal for rapid application development and deployment.
Ch supports an increasing number of third party software applications. It includes Ch Control toolkit, Ch Mechanism Toolkit, Ch NAG Statistics Package, Ch CGI toolkit, Ch ODBC toolkit, Ch XML toolkit, ChExcel for manipulating Microsoft Excel in C/C++ scripts,
Intel OpenCV for computer vision, ImageMagick for
image processing, National Instruments' data acquisition toolkit NI-DAQ and motion control toolkit NI-Motion.
