Ch 4.7, Ch SDK 4.7 and Embedded Ch 4.7 Released

DAVIS, California, September 28, 2004 - SoftIntegration, Inc. today announced
the availability of Ch 4.7, Ch SDK 4.7 and Embedded Ch 4.7. Ch is an
embeddable C/C++ interpreter for cross-platform scripting, 2D/3D plotting,
numerical computing, shell programming and embedded scripting.

Ch, Ch SDK and Embedded Ch version 4.7 are the most stable release. They are
significantly improved for embedded scripting. Ch shell is more compatible
with C shell in both command mode and shell programming.

Thirty-six new APIs are added in Ch SDK and Embedded Ch for easier interface
with binary C/C++ libraries and embedded scripting. Major product
enhancements for Ch SDK and Embedded Ch include input/output redirection,
obtaining complete information about variables and functions in a Ch script,
and interfacing functions with a variable number of arguments.

"Ch and Embedded Ch toolkit provide a framework and development environment
that enabled the development of an extremely flexible Automatic Test
Equipment (ATE) environment. The standard ANSI C/C++ support makes training an
issue of the past. The performance of the Ch interpreter far exceeded our
expectations. The technical support from SoftIntegration was exceptional and
sets a standard for other developers to achieve." said Errol Korpinen, Manager
for Test Technology Development at Skyworks Solutions, Inc. "I strongly
recommend Embedded Ch for all people developing Script based Test
Environments."

"SoftIntegration provides an unmatched level of power and flexibility in
C/C++ scripting and embedded scripting," added Dr. Dawn Cheng,
President at SoftIntegration. "The release of Ch, Ch SDK and Embedded Ch
version 4.7 is our commitment to meet our customers' request for powerful
script computing."

This new release supports Borland compiler for embedded scripting. Sample
code using VC++, VC.NET, and Borland compiler to embed Ch into C/C++
applications are included in the distribution.

* C/C++ interpreter

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, and CGI.
Functions in static or dynamical binary C/C++ libraries can be executed
interpretively in scripting without re-compilation using Ch SDK.

* 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 100 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.

* 2D/3D plotting and numerical computing

Ch supports 2D/3D graphical plotting, C LAPACK, advanced high-level numerical
functions. Ch has built-in 2D/3D plotting support, generic mathematical
functions and computational arrays for linear algebra and matrix computations,
and 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 numerical extensions are the best choice for numerical computing in the
C/C++ domain. 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 is ideal for rapid application development and deployment. For example, a
Control System Toolkit for design and analysis of linear time-invariant
control systems developed in Ch is available.

* Interface with binary C/C++ libraries

Ch SDK 4.7 can easily integrate existing C/C++ libraries as part of Ch
scripting modules. Functions and classes in static or dynamical libraries can
be invoked in a Ch script file or Ch command shell.

* Embeddable scripting

Ch 4.7 is optimized for embedded scripting. Embedded Ch allows users to embed
Ch into other C/C++ application programs and hardware. 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 on-line. Embedded Ch has a small
footprint. The pointer and time deterministic nature of the C language
provides a perfect interface with hardware in real-time systems.

* Ch toolkits and third party software support

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, Intel OpenCV for computer vision and image
processing, National Instruments' data acquisition toolkit NI-DAQ and motion
control toolkit NI-Motion, Barret Technology's Barret Hand robotic manipulator
control, and Perl Compatible Regular Expressions, as well as IDE (Integrated
Development Environment).

Pricing and Availability

Ch and Embedded Ch for Windows, Linux, Mac OS X, Solaris, HP-UX and FreeBSD
are available. Ch Standard Edition is free for both commercial and
non-commercial uses in all platforms. Ch Professional Edition is free for
academic use and costs $399 for personal or commercial use.
