Hitachi, Ltd.(NYSE:HIT) today announced the release of the
H8S and H8/300 series C/C++ compiler supporting the C++ language, suited
to object-oriented program development, as a development environment for
Hitachi 8/16-bit microcontrollers. The new compiler will go on sale in
November 1998 in Japan.
Hitachi has previously developed an optimized C compiler for the H8S
and H8/300 series, featuring extended embedding-oriented functions, as
a development environment for H8/300L series, H8/300 series, H8/300H series,
H8/2000 series, and H8/2600 series microcontrollers, but with the continuing
trend toward shorter product development cycles and larger programs, the
burden of software development, amendments, and maintenance has increased
sharply, and there is a growing demand for support for the C++ object-oriented
language, with its excellent program reusability and serviceability characteristics.
At the same time, there is a need for further improvement in ROM efficiency
for embedded applications.
The newly developed H8S and H8/300 series C/C++ compiler conforms to
ANSI*1/ISO standard C++ language specifications, and offers
program development that exploits the C++ features of program reusability
and serviceability. The new compiler also conforms to Embedded C++*2language
specifications through support for Embedded C++ specification options and
an Embedded C++ class library.
Hitachi Debugging Interface (HDI) running in a MicrosoftR
WindowsR 95*3 environment, or Integrated Debugging
Manager (IDM) running in a UNIX*4 environment, is provided as
standard as a debugging environment, allowing C++ source-level debugging
to be carried out easily using the mouse. Also included as standard is
an integrated development environment that features browser tools offering
visual analysis and display of class inheritance relationships, function
call relationships, and symbol searches, and organic linking of these tools,
via a user-friendly window-based interface. This software enables program
development and amendment efficiency to be improved by a factor of 2 to
3.
Sharing the optimized processing and code generation sections of the
previous compiler provides source-level optimization such as deletion of
common expressions and register allocation, plus comprehensive extended
functions designed for embedded applications and link-time optimization
that extends across a number of source files. Also, the addition of optimization
functions specific to C++ makes it possible to generate object code (with
a ratio of 1.0 with respect to C language) that takes account of ROM efficiency
even when using C++.
This new product offers a common C++ development environment for 8-,
16-, and 32-bit microcomputers, together with the SuperHTM*5
RISC engine family, and at the same time enables common C++ program resources
to be constructed.
