ABSTRACT:
BACKGROUND
This invention relates generally to operating systems and particularly to systems for converting software designed to operate on one operating system, such as Windows® 95 or Windows® NT, to run on another operating system, such as Windows® CE.
Microsoft® Windows® CE is a 32 bit operating system designed particularly for use with small computers such as handheld and palmtop computers. Handheld and palmtop computers are a class of computers with relatively limited capabilities, designed to be smaller than portable, laptop or notebook computers in size. Thus, the Windows® CE operating system is smaller, in terms of memory footprint and functionality, than other Windows® operating systems. Many of the components of Windows® CE are modular so that a system developer may use certain portions of the operating system as needed.
Windows® CE uses a subset of the Windows® 32 bit application program interfaces (API). Developers of Windows® CE software can use the same development tools that are used for other Windows® 32 bit applications.
Software that is designed to operate with the Windows® 95 and NT operating systems cannot be used with the Windows® CE operating system without recompiling source code, and in most cases without rewriting source code. This means the amount of software available for use in Windows® CE machines is relatively limited compared to that for other Windows® operating systems.
While Microsoft suggests that Windows® 95 programs may be ported to Windows® CE (see “Porting Windows® 95 Programs to Windows CE” at http//www.microsoft.com/Windowsce/embedded/techpapers/wce20/porting.asp), Microsoft concedes that rewriting and recompiling source code is necessary. Thus, there is a tremendous demand for a system that enables other Windows® 32 bit applications to be used with the Windows® CE operating system.
SUMMARY
In one embodiment, a method of converting software to run on different operating systems includes loading software on a first computer system having a non-Windows CE operating system. The software is translated to run on a second computer system, having a Windows® CE operating system, without recompiling the source code. This software then may be transferred to a second computer system running a Windows® CE operating system.
