Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online application distribution services face challenges in generating highly optimized application code for diverse terminals, as current methods either require manual porting and optimization for each processor or rely on virtual machines that do not achieve performance equivalent to offline compilers, leading to suboptimal execution.
Innovation Solution
A method utilizing compilers to generate dedicated application code from a single original code for specific terminals, incorporating optimizations for better performance, memory access, and energy efficiency, allowing for automatic generation and distribution of optimized code across various platforms, including those with different processors and APIs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual machine is used to execute intermediate code on multiple terminals, then compatibility across different platforms is improved, but execution speed and performance optimization deteriorate
Solution Approach 1:
The patent segments the code compilation process by generating multiple specialized binary code versions from a single intermediate code, each optimized for specific terminal types (iPhone, iPad, Android devices with different processors). This allows the system to maintain platform compatibility through intermediate code while delivering optimized native binary code to each terminal type, thus resolving the contradiction between compatibility and execution speed
Solution Approach 2:
The patent implements preliminary compilation action by pre-compiling intermediate code into multiple terminal-specific binary code versions before distribution. The compilation server proactively generates optimized binary code for different terminal types in advance, so that when users download applications, they receive already-optimized code rather than requiring runtime compilation, thereby improving execution speed while maintaining compatibility
2Speed
If binary code is generated for each processor type, then execution performance is improved, but development complexity and time increase
Solution Approach 1:
The patent introduces an intermediary compilation server that acts as a mediator between the developer's single intermediate code and multiple terminal-specific binary codes. The developer only needs to compile once to intermediate code, and the compilation server automatically handles the generation of multiple optimized binary versions for different processors, thus improving execution performance while reducing development complexity
Solution Approach 2:
The patent uses copying by creating multiple binary code copies from a single intermediate code source, each copy being optimized for a specific terminal type. This allows the system to generate processor-specific optimized code without requiring the developer to manually create separate codebases for each platform, thereby improving execution performance while simplifying the development process
3Ease of manufacture
If a runtime system is used to abstract terminal-specific parts, then ease of development is improved, but code optimization capability deteriorates
Solution Approach 1:
The patent segments the code delivery process by separating the universal intermediate code (which provides ease of development through runtime abstraction) from terminal-specific optimized binary codes (which provide manufacturing precision through native optimization). The system delivers both: the intermediate code maintains developer ease, while the generated binary codes achieve native-level optimization for each terminal type
Solution Approach 2:
The patent applies preliminary optimization action by pre-compiling intermediate code into terminal-specific binary codes before distribution. This preliminary compilation step captures optimization opportunities that would be lost in runtime execution, achieving native-level code optimization while the developer continues to work with the easier-to-use intermediate code through the runtime system
