Dynamic Translator Shadow Memory JIT Compilation

The patent applies preliminary action by pre-compiling translation code sequences before they are needed. A compilation queue maintains precompiled native code sequences corresponding to non-native instruction sequences. When non-native code is encountered, the system checks if a precompiled sequence exists, avoiding runtime translation overhead. This resolves the contradiction by preparing translation mappings in advance while maintaining the ability to execute non-native code dynamically.

The patent implements dynamics by creating a hybrid translation system that adapts between different execution modes. The system dynamically selects between executing precompiled native sequences and performing runtime translation based on availability. A compilation queue dynamically manages which non-native sequences need precompilation, allowing the system to balance between adaptation capability and execution speed based on runtime conditions.

The patent applies preliminary action by pre-analyzing and compiling non-native instruction sequences into native code before execution. The compilation queue stores preprocessed translation mappings that include opcode, source, and destination location information. During runtime, the system retrieves these precompiled sequences without performing parsing operations, maintaining translation accuracy while eliminating decoding overhead.

The patent introduces an intermediary compilation queue that acts as a buffer between non-native code and native execution. This intermediary structure stores precompiled translation sequences, allowing the system to separate the complex parsing and compilation work from the execution path. The intermediary maintains translation accuracy by preserving detailed instruction mappings while improving productivity by providing direct access to compiled sequences during runtime.

The patent applies merging by combining multiple individual instruction translations into batch processing. Instead of translating each non-native instruction individually through a simple loop, the system groups sequences of non-native instructions and compiles them together into native code blocks. This merging approach maintains implementation simplicity by building on the loop-based structure while dramatically improving execution performance through reduced translation overhead and optimized native code generation.

The patent applies preliminary action by performing compilation work in advance of execution. The compilation queue identifies and compiles sequences of non-native instructions before they need to be executed. This preliminary compilation transforms the simple loop-based translation approach into a two-phase system: a compilation phase that prepares optimized native code, and an execution phase that runs the precompiled code directly, thereby improving performance without complicating the core translation logic.
