Processor Instruction for Packed Data Control Index Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processors require numerous instructions to generate control indexes for packed data rearrangement, leading to increased processing time, resource utilization, and power consumption, and often result in control indexes being regenerated or retrieved from memory, which is inefficient.
Innovation Solution
Incorporating instructions that can generate control indexes entirely within a single macroinstruction, using sequences of non-negative integers following numerical patterns, such as consecutive or offset integers, to reduce the number of instructions needed and improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multi-instruction methods are used to generate control indexes, then control indexes can be generated with basic processor instructions, but processing time increases and resource utilization increases
Solution Approach 1:
The patent combines multiple separate instructions (load instruction, arithmetic instructions for generating sequence) into a single specialized instruction that directly generates control indexes. This merging eliminates the need for multiple sequential operations, thereby reducing processing time while maintaining the capability to generate control indexes.
Solution Approach 2:
The patent implements preliminary action by pre-defining numerical patterns (such as consecutive sequences, strided sequences) that can be directly generated by the instruction without requiring runtime computation. This allows control indexes to be generated immediately from predefined patterns rather than computing them from scratch each time.
2Reliability
If traditional multi-instruction methods are used to generate control indexes, then control indexes can be generated with standard instructions, but resource utilization increases
Solution Approach 1:
The patent merges multiple processor instructions into a single specialized instruction for generating control indexes. This reduces the total number of instructions that need to be fetched, decoded, and executed, thereby improving processor productivity and reducing resource utilization while maintaining full control index generation capability.
Solution Approach 2:
The specialized instruction is self-service in that it directly generates control indexes without requiring auxiliary arithmetic instructions or memory operations. The instruction encapsulates the entire generation logic internally, eliminating dependencies on other processor resources and improving overall system productivity.
3Reliability
If control indexes are regenerated frequently, then up-to-date control indexes are available, but processing time increases and resource utilization increases
Solution Approach 1:
The patent applies preliminary action by embedding predefined numerical patterns directly in the instruction, allowing control indexes to be generated immediately from these patterns when needed. This eliminates the need for frequent regeneration from scratch, as the predefined patterns can be quickly instantiated to produce accurate control indexes on demand.
4Reliability
If control indexes are stored in memory, then control indexes can be reused, but retrieval from memory increases processing time
Solution Approach 1:
The patent merges the control index generation functionality directly into the processor instruction stream, allowing control indexes to be generated and reused without requiring memory retrieval. This eliminates the memory access bottleneck while maintaining reusability, as the same instruction can be executed multiple times to generate identical control indexes when needed.
