ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
This invention relates generally to translation systems for computer programs, and more particularly to an interactive translation system and method.
BACKGROUND OF THE INVENTION
A digital signal processor (DSP) is a computer chip adapted for a particular purpose. DSPs are used to electronically process digitized analogue or digital signals. The signals may be voice, data, radio, or other similar signals. DSPs are often found in telephony systems, radio systems, CD players, computers, and TVs.
DSPs are typically programmed using assembly language. Assembly language is used because it allows for the creation of highly optimized programs for the DSP. Assembly language may also be used because of a lack of tools, such as compilers, available for the DSP. As new DSP chips replace older DSP chips, the assembly language used on the new DSP chips is often different from the assembly language used on the old DSP chips. Thus, in order to utilize new DSP chips, assembly language programs for old DSP chips must be rewritten for new DSP chips.
Rewriting an assembly language program from an old DSP chip to work on a new DSP chip is a tedious, time consuming and difficult process. Typically, the rewriting is done manually, with the programmer starting from scratch and writing the entire program for the new DSP chip, or by using simple tools, or by using simulators that run the old DSP program on the new DSP chip. These methods are problematic because they are slow and prone to inaccuracies or inefficiencies.
SUMMARY OF THE INVENTION
In accordance with the present invention, an interactive translation system and method are provided that substantially eliminate or reduce disadvantages and problems associated with previously developed translation or migration systems and methods. In particular, the interactive translation system and method combine static translation with an interactive environment in order to provide both accurate and efficient translations with minimal user intervention.
In one embodiment of the present invention, an interactive translation system includes a front end, a back end, and a user interface. The front end is operable to identify source elements in a source file. The back end is operable to generate a translation file having translation elements corresponding to translation of the identified source elements and having an interface for receiving inputs for modifying the translation.
More specifically, in accordance with one embodiment of the present invention, the source and translation files are assembly language files. In this and other embodiments, the source and the translation files may be for disparate source and target devices or disparate formats for a same device.
In another embodiment, a method for performing translation is provided. The method receives a source file and identifies source elements in the source file. The method generates a translation file having translation elements for a target device by performing a context-dependent translation of the source elements. The method displays the translation elements in an interface for receiving user inputs and in response to user inputs automatically regenerates selected translation elements based on the user input.
Technical advantages of the present invention include providing an improved translation system and method. In particular, the translation system and method combine static analysis of a source program with an interactive environment that prompts a user for information about the source program that is not statically determinable. The static analysis provides for efficient translation while the interactive environment provides information not available from static analysis. In this way, the translation is both accurate and efficient.
Other technical advantages will be readily apparent to one skilled in the art from the following figures, description, and claims.
