bytecode interpreter การใช้

• The bytecode interpreter is written in C ( _ sre . c ).
• No external run time libraries are needed; the bytecode interpreter is self-contained.
• This " compiled " code is then interpreted by a bytecode interpreter ( itself written in C ).
• Butte compiled into Butte-specific byte codes, which were interpreted by special Alto microcode, similar to the Mesa bytecode interpreter.
• The term " bytecode interpreter " has a specific meaning, that the intermediate language is interpreted opcode by opcode by a software loop.
• The compiled code in this case is machine code for a virtual machine, which is implemented not in hardware, but in the bytecode interpreter.
• The GNU implementation has numerous extensions beyond the POSIX standard and is no longer a front-end to dc ( it is a bytecode interpreter ).
• Control tables-that do not necessarily ever need to pass through a compiling phase-dictate appropriate algorithmic control flow via customized interpreters in similar fashion to bytecode interpreters.
• On June 2, 2008, the WebKit project announced they rewrote JavaScriptCore as " SquirrelFish ", a bytecode compiles JavaScript into native machine code, eliminating the need for a bytecode interpreter and thus speeding up JavaScript execution.
• However, for interpreters, an AST causes more overhead than a bytecode interpreter, because of nodes related to syntax performing no useful work, of a less sequential representation ( requiring traversal of more pointers ) and of overhead visiting the tree.
• In 1985-7, a team from Fuji Xerox developed a C implementation of the microcoded bytecode interpreter, and, together with Xerox AI Systems ( XAIS ) in Sunnyvale, California, completed the port of the environment and emulator to the Sun Microsystems SPARC 4 architecture.
• After booting the propeller a bytecode interpreter is copied from the built in ROM into the 2 KB RAM of the primary COG . This COG will then start interpreting the bytecodes in the main 32 KB RAM . More than one copy of the bytecode interpreter can run in other COGs, so several Spin code inline " inserted.

• Also, assembly can sometimes be portable across different operating systems on the same type of CPU . Calling conventions between operating systems often differ slightly or not at all, and with care it is possible to gain some portability in assembly language, usually by linking with a platforms with an overhead no greater than a typical bytecode interpreter.
• In 1999, when id Software released the code from Quake's engine under the GNU General Public License ( GPL ), the workings of the bytecode interpreter were examined and new QuakeC compilers were released, such as J . P . Grossman's qccx and a new version of FrikQCC . These compilers took advantage of newly discovered features in a backwards-compatible way so that the bytecode could still be properly interpreted by unmodified Quake engines.
