Abstract (en)

[origin: WO0122213A2] The invention relates to a method of optimizing interpreted programs, in a virtual machine interpreter of a bytecode-based language, comprising means for dynamically reconfiguring said virtual machine with macro operation codes by replacing an original sequence of simple operation codes with a new sequence of said macro operation codes. The virtual machine interpreter is coded as an indirect threading interpreter thanks to a translation table containing the implementation addresses of the operation codes for translating the bytecodes into the operation code's implementation addresses. Application: embedded systems using any bytecode-based programming language, set to box for interactive video transmissions.
