The Windows 95 and Windows NT versions of MULTI are fully compliant with the Win32 API. Incorporating a common look and feel, both versions support the Windows interface controls, desktop color scheme, clipboard cut and paste facilities, I/O dialog boxes, and proportional Windows scrollbars.

The Windows and UNIX versions of MULTI feature a new graphical toolbar for performing common operations. They also feature support for third party editors, an interface for launching external command line tools and applications, and user-customizable check-in/check-out functions for version control.

"With Version 1.8," remarked Green Hills president Dan O'Dowd, "MULTI is now fully integrated with Windows 95 and Windows NT. In addition, MULTI now provides a uniform set of capabilities that are consistent for both Windows and UNIX platforms."

The MULTI Development Environment, together with Green Hills' family of optimizing compilers, automate every aspect of C, C++, FORTRAN, Pascal and Ada 95 software development, from editing and source-level debugging, to run-time error checking, application profiling, and project/version control.

MULTI's program builder, editor, and debugger are tightly integrated to offer quick, convenient single- and double-click transfers between debug mode and full source editing. For example, simply clicking on a compiler error message brings the user to the editor, opens the file containing the error, moves the cursor to the line containing the error, and highlights the error.

Applications developed under MULTI on a Windows or UNIX system can be cross compiled for execution on most major RISC and CISC CPUs, including the PowerPC, 68k, CPU32, ColdFire, SPARC, MIPS, SH, V800, i960, and x86 architectures. The compiled code can run on the target CPU in a bare bones mode: under Green Hills' own velOSity and INTEGRITY real-time operating systems; under Wind River Systems' VxWorks operating system; under custom real-time operating systems; under a variety of processor-specific in-circuit emulators (ICEs); and on targets that support BDM/JTAG interfaces.

The heart of the MULTI environment is an RTOS-aware source-level debugger that features process- and system-level debug capabilities. The debugger supports mixed assembly and high-level language formats, includes a language-sensitive expression evaluator, and provides special support for C++ (such as a Class Browser, object display and template debug capability) and X-Windows debugging.

The MULTI debugger is fully RTOS aware, enabling designers to debug and tune their applications at a task level. With the MULTI debugger, designers can start and stop tasks, set task-specific breakpoints, and monitor OS resources like buffers, queues, and streams. Programmers can also debug new tasks as they are spawned and watch processes as they communicate through pipes and semaphores.

MULTI's debugger can provide a separate window for each process. Within each window, programmers can independently set conditional and temporary breakpoints, single step, and examine local and global variables. Complex expressions and structured elements such as arrays and records can also be displayed. The debugger recognizes pointers and automatically displays the objects that they reference. It also displays a stack trace that simplifies the analysis of hierarchical program structure.

MULTI's run-time error checker detects memory leaks and common program faults such as out-of-bounds array subscript, storing values into variables or bit fields that are too small to hold them, and attempting to access unallocated memory.

MULTI's profiler helps programmers identify hot spots by providing program run-time data on a function by function and line by line basis, performance statistics, code coverage analysis, and more. MULTI's windowing editor features scroll bars, pull-down menus, and buttons for common commands. The editor is fully configurable, enabling users to change key bindings and alter object (such as scroll bars) behavior based on their application requirements. Programmers can also substitute their own editor.

MULTI's Project Control system simplifies the design of large projects by providing automated build tools that eliminate the need for a make expert. MULTI's Version Control system augments the build tools by simplifying the management of revision levels and multiple project branches of project (i.e., developing two versions of software at the same time).

MULTI is fully integrated with a number of RTOSs and other target environments for seamless Windows NT-hosted embedded development. These environments include Green Hills' own velOSity and INTEGRITY RTOSs, the Green Hills ROM Monitor, Wind River Systems' Tornado/VxWorks, HP Processor Probes and HP 64700 ICEs, Hitachi ICE for SH, Intel i960 ROM Monitor, and systems supporting BDM/JTAG.
