Unified Load and Duplicate Scalar Data Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital signal processors require multiple instructions for loading scalar data and duplicating it, which is inefficient and occupies additional execution slots.
Innovation Solution
The load and duplicate operation is combined into a single operation, allowing for the specification of duplication patterns such as byte, half word, word, or double word duplication, freeing up one execution slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate load and duplicate instructions are used, then data loading and duplication can be performed, but execution slots are consumed and processing efficiency is reduced
Solution Approach 1:
The patent combines the load operation and duplicate operation into a single unified instruction called 'load and duplicate'. This merging eliminates the need for separate instructions, reducing the total instruction count and freeing up execution slots in the processor pipeline, thereby improving processing efficiency without adding device complexity
2Speed
If multiple instructions are used for loading and duplicating scalar data, then complete data processing can be achieved, but execution slots are occupied and processing speed decreases
Solution Approach 1:
By merging the load and duplicate operations into a single instruction, the processor can complete both operations in one execution cycle rather than requiring multiple sequential instructions. This reduces the total execution time and increases data processing speed by eliminating the time loss associated with multiple instruction fetches and executions
