Instruction Translation Program Generation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developers face a significant burden when translating complex instruction sets into simple ones, as they need to manually analyze mnemonics and operands to produce translation programs, and this burden increases with the expansion of the instruction set, leading to potential errors and inefficiencies.
Innovation Solution
A computer-readable recording medium stores a program that generates a translation program based on a table data set mapping operand patterns to instructions, allowing for the automatic translation of code from a complex instruction set to a simple one, reducing the manual effort required and enabling efficient expansion of the instruction set without modifying the translation program.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a translation program manually analyzes mnemonics and operands to translate complex instruction sets into simple ones, then translation accuracy is improved, but the implementation burden and development time increase significantly
Solution Approach 1:
The patent pre-defines mapping relationships between complex instructions and simple instructions in a data structure before translation occurs. This preliminary preparation eliminates the need for manual analysis during translation, as the system simply retrieves pre-established mappings based on instruction mnemonics and operand patterns.
Solution Approach 2:
The patent replaces manual mechanical analysis of mnemonics and operands with an automated information retrieval system. Instead of developers manually analyzing each instruction, the system automatically queries pre-defined mapping data to generate translations, substituting human intellectual labor with automated data-driven processes.
2Adaptability or versatility
If the translation program is manually modified to accommodate expansion of the instruction set, then translation capability is improved, but the maintenance complexity and error risk increase
Solution Approach 1:
The patent segments the translation system into independent mapping entries for each instruction type. Each instruction has its own predefined mapping relationship that can be added or modified independently without affecting other instructions. This modular segmentation allows easy expansion while maintaining system stability.
Solution Approach 2:
The patent establishes a framework where all translation mappings are pre-defined in advance. When the instruction set expands, new mappings are simply added to the pre-established data structure rather than requiring modification of existing translation logic, enabling maintenance-free expansion.
3Manufacturing precision
If one instruction in the complex instruction set is translated into a combination of two or more simple instructions, then translation accuracy is improved, but the translation program complexity increases
Solution Approach 1:
The patent pre-determines the exact combination of simple instructions that should replace each complex instruction based on predefined mapping rules. This eliminates the need for real-time decision-making during translation, as the system simply retrieves pre-planned instruction combinations from the data structure.
Solution Approach 2:
The patent uses template-based copying of instruction patterns. Predefined mapping entries serve as templates that automatically generate the correct sequence of simple instructions for each complex instruction type, eliminating the need for complex conditional logic and reducing program complexity.
Data Source
AI summary
A process includes receiving a table data set that represents mappings between a plurality of operand patterns indicating types of operands possibly included in a first instruction used in a first assembly language and a plurality of second instructions used in a second assembly language or a machine language corresponding to the second assembly language. The table data set maps two or more of the second instructions to each of the operand patterns. The process also includes generating, based on the table data set, a translation program used to translate first code written in the first assembly language into second code written in the second assembly language or the machine language. The translation program defines a process of determining an operand pattern of an instruction included in the first code and outputting two or more instructions of the second code according to the determined operand pattern.
