		Binary Translation 1 Abstract Binary translation is a technique used to change an executable program for one computer architecture and operating system into an executable program for a different computer architecture and operating system.
		Translators can be classified as either (1) bounded translation systems, in which all the instructions of the old program must exist at translate time and must be found and translated to new instructions,[3,4,5] or (2) open-ended translation systems, in which code may also be discovered, created, or modified at execution time.
		The idea of binary translation is becoming more common in the computer industry, as various other companies start on their transitions to 64-bit architectures.

	Just-in-time compilation - Wikipedia, the free encyclopedia
		In computing, just-in-time compilation (JIT), also known as dynamic translation, is a technique for improving the performance of bytecode-compiled programming systems, by translating bytecode into native machine code at runtime.
		In a bytecode-compiled system such as Perl, GNU CLISP, or early versions of Java, source code is translated to an intermediate representation known as bytecode.
		Dynamic translation was pioneered by the commercial Smalltalk implementation currently known as VisualWorks, in the early 1980s.

		Previous binary translators built by DIGITAL also depended on the presence of an emulator in this role.[5] Emulator performance is more of an issue for FX!32 because, unlike those earlier binary translators, all application code is interpreted when the x86 application is first run.
		The x86 addresses for which there are translated routines and the address of the corresponding translated code are entered into the hash table by the runtime when it loads an x86 image that has been translated.
		Having the emulator return to translated code on a return instruction minimizes the amount of time that is spent in the emulator; however, the emulator can only return to the translated code if it knows that it has a valid return address.

	Program Transformation Wiki / Binary Translation
		Binary tanslation is the process of automatically translating binary object code from one machine Mi to another.
		In this case we are interested in both translating the applications from the source machine, but also in trapping or translating the operating system calls from the source machine to the operating system supported on the target machine.
		In this case this is not really binary translation, rather we are interested in trapping operating system calls from the application compiled for the source machine to use the operating system API on the target machine, like Wine on Linux x86 machines.

	Java Bytecode Compilation - a Special Case of Binary Translation
		Binary translation is a form of compilation where the source language is a machine and not a high level language.
		Binary translation is rather an old technique and various examples of its application are described in the literature.
		Because of that, binary translators usually devote much effort to the disassembly phase in order to detect as much code as possible, whereas aggressive optimization and code generation is neither possible nor useful.

	BEA WebLogic XML/Non-XML Translator Overview
		Binary data is not self-describing, so in order to be understood by an application, the layout of this data (metadata) must be embedded within each application that uses the binary data.
		It is this description of the binary data that is used to translate the binary data to XML.
		MFL documents are metadata used by the run-time component of XML Translator to translate an instance of a binary data record to an instance of an XML document (or vice-versa).

	Timing Insensitive Binary-to-Binary Translation (TIBBIT)
		TIBBIT builds upon previous work in binary-to-binary translation (BBT), where the object code of an application is analyzed using control and dataflow analysis, and instruction sequences (e.g., basic blocks) are then translated from the source ISA to the target ISA, preserving the semantics of the program.
		During translation the time required to execute each basic block is computed for the source ISA, and this is used to modulate the speed at which the application executes on the target ISA.
		Translated systems retain timing equivalence with the original systems to within 80 microseconds while scheduled under the Rate Monotonic Scheduling algorithm on the target with other tasks (Figure 1), and within 25 microseconds when executing on a dedicated processor.

		A dynamic binary translation system for a co-designed virtual machine is described and evaluated.
		Because the underlying superscalar microarchitecture is capable of dynamic instruction scheduling, the binary translation system does not perform aggressive optimizations or reschedule code; this significantly reduces binary translation overhead.
		Detailed timing simulation of the dynamically translated code running on an accumulator-based distributed microarchitecture shows the overall system is capable of achieving similar performance to an ideal out-of- order superscalar processor, ignoring the significant clock frequency advantages that the accumulator-based hardware is likely to have.

		Translation, sometimes called software emulation, has been studied extensively in academic research and to an extent is offered by the Crusoe processor from Transmeta Corp. (Santa Clara, Calif.).
		The Dynamite architecture is based around a translation kernel, with a front end that takes code aimed at a source processor and a back end that aims the translation at a new target.
		Binary translation rides on "advances in processor technology and software maturity," he said.

		If only the name of the input binary file is provided on the command line, TOXFR will generate a name for the output transfer file that has the same base name as the input binary file and an appropriate filename extension, based on the filename extension of the binary file.
		In the first example, the name for the binary file produced is derived from the name of the transfer file, using the full base name and replacing the letter `x' in the file name extension with the letter `b', to indicate that the file is a binary file.

		Nobody complains about the overheads inherent in this form of binary translation however it is clear that the CPU will run hotter, and consume more power in order to translate ia32 code into something that is optimised for the CPU.
		That's where binary translation fits in and can squeeze out some extra speed if needed and unlike hardware, software can be updated frequently to include even more exotic forms of optimisation.
		And with present technology, binary translation is a faster means of achieving correctness than hardware virtualization.

		I expect if VMware (and other binary translators) are willing to cache results to a separate disk area and spend more time optimising off-line the results would mitigate the initial translation speed hit.
		The OS code that is being binary translated is some of the most highly optimized, hand-tuned code in existence.
		It's already the expensive path for the OS, and no binary translator is going to improve upon that without a huge amount of upfront overhead.
