Neural Network Instruction Reuse via Hash Table Lookup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of machine learning and pattern recognition algorithms in neural networks leads to longer instructions for hardware components, consuming more time and power, especially with increasing numbers of layers in multilayer neural networks, where conventional instruction generation methods are inefficient.
Innovation Solution
A neural network instruction reuse device calculates a hash value for each layer and checks if it exists in a hash table; if it does, previously generated instructions are reused with modifications, otherwise, new instructions are generated and stored in the hash table for future reuse.

Engineering Contradiction Analysis
1Reliability
If conventional instruction generation methods are used for each neural network layer, then complete and accurate instructions are generated for all layers, but the time and power consumption increase significantly with increasing numbers of layers
Solution Approach 1:
The system performs preliminary actions by generating instructions for the first neural network layer and storing them in a hash table before processing subsequent layers. When generating instructions for later layers, the system checks the hash table for existing instructions that can be reused, thereby avoiding redundant generation and reducing overall processing time while maintaining accuracy through selective regeneration when necessary
Solution Approach 2:
The system recovers and reuses previously generated instructions for neural network layers by checking the hash table. Instead of discarding and regenerating instructions for each layer, the system recovers existing instructions when they match the current layer requirements, significantly reducing the time and power consumption associated with repeated instruction generation
2Reliability
If instructions are generated for each neural network layer independently, then all layers receive optimized instructions, but the power consumption increases with increasing numbers of layers
Solution Approach 1:
The system performs preliminary instruction generation and storage in the hash table before processing subsequent layers. This preliminary action enables the system to reuse instructions for later layers without requiring full regeneration, thereby reducing the cumulative power consumption while still providing layer-specific optimization through selective instruction generation and modification
Solution Approach 2:
The system recovers and reuses previously generated instructions by checking the hash table before generating new ones. This recovery mechanism avoids redundant instruction generation for subsequent layers, significantly reducing the power consumption associated with independent instruction generation for each layer while maintaining optimization through selective regeneration when layer characteristics change
3Productivity
If the instruction generation process is simplified to reduce time and power consumption, then efficiency improves, but the complexity of handling different neural network layer configurations increases
Solution Approach 1:
The system introduces a hash table as an intermediary mechanism between the instruction generation process and the neural network layer processing. This intermediary stores and manages instructions efficiently, enabling the system to quickly retrieve and reuse appropriate instructions for different layer configurations without adding significant complexity to the overall process. The hash table acts as a mediator that simplifies the handling of varying layer configurations through efficient lookup and reuse operations

AI summary
Aspects of reusing neural network instructions are described herein. The aspects may include a computing device configured to calculate a hash value of a neural network layer based on the layer information thereof. A determination unit may be configured to determine whether the hash value exists in a hash table. If the hash value is included in the hash table, one or more neural network instructions that correspond to the hash value may be reused.
