Solution Overview
Problem
Current processors with SIMD architectures face limitations in efficiently combining packed data operation mask registers, which hinders the execution of complex arithmetic operations on multiple data elements in parallel, leading to suboptimal performance in tasks requiring simultaneous processing of large datasets.
Innovation Solution
The introduction of packed data operation mask register arithmetic combination instructions and processors capable of executing these instructions, allowing for the arithmetic combination of packed data operation mask registers, enabling more efficient processing of multiple data elements by using masked packed data operations that conditionally perform operations on individual data elements or pairs, thereby enhancing code density and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional SIMD architectures are used to process packed data, then processing speed is improved, but the ability to efficiently combine packed data operation mask registers deteriorates
Solution Approach 1:
The patent combines the functionality of packed data operation mask registers with arithmetic combination capabilities, merging previously separate operations into a unified instruction that can perform both masking and arithmetic combination in parallel, thereby resolving the contradiction between maintaining processing speed and gaining versatility in mask register operations
2Productivity
If arithmetic combination of packed data operation mask registers is implemented, then code density and throughput are improved, but device complexity increases
Solution Approach 1:
The patent implements universal packed data operation mask register arithmetic combination instructions that can perform multiple arithmetic operations (addition, subtraction, multiplication, division) on mask registers using a single instruction format, thereby improving instruction throughput without proportionally increasing device complexity
3Manufacturing precision
If conditional control over individual data elements is added, then manufacturing precision of operations is improved, but ease of operation deteriorates
Solution Approach 1:
The patent segments the packed data operation mask into individual controllable elements, allowing conditional control over each data element or pair through separate mask bits, thereby achieving precise control over arithmetic operations on specific elements while maintaining a unified instruction structure that does not overly complicate operation
