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 the regeneration or retrieval of these indexes, which can be inefficient.

Innovation Solution

Incorporating instructions and processors capable of generating control indexes entirely within a single macroinstruction, using sequences of non-negative integers with specific numerical patterns, such as consecutive or offset integers, to reduce the number of instructions needed and improve efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If traditional multi-instruction methods are used to generate control indexes, then processing accuracy is maintained, but processing time and resource utilization increase

Engineering Contradiction:

Improveprocessing timeVSAvoidnumber of instructions

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent combines multiple instructions into a single macroinstruction that performs both control index generation and packed data rearrangement operations. This merging eliminates the need for separate instruction sequences, reducing processing time and instruction count while maintaining the required processing accuracy through integrated execution logic.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The macroinstruction incorporates preliminary generation of control indexes within its execution flow, performing index calculation and data rearrangement in a predetermined sequence. This preliminary action embedded within the single instruction eliminates the need for separate preliminary instruction sequences, directly reducing the total number of instructions required.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If control indexes are generated using multiple instructions, then comprehensive data rearrangement is achieved, but resource utilization and power consumption increase

Engineering Contradiction:

Improvedata rearrangement efficiencyVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent merges control index generation and packed data rearrangement into a single macroinstruction, reducing the total instruction count and associated power consumption. The integrated execution unit processes both operations in one instruction cycle, improving data rearrangement efficiency while lowering energy usage compared to sequential multi-instruction execution.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The macroinstruction performs self-service by generating its own control indexes internally during execution, eliminating the need for external index generation routines. This self-contained approach improves productivity through autonomous operation while reducing power consumption by avoiding additional instruction fetch and execution cycles.

Inventive Principle:

Principle #25Self-service

3Reliability

If traditional instruction sequences are used, then control indexes can be generated, but the indexes often require regeneration or retrieval

Engineering Contradiction:

Improvecontrol index availabilityVSAvoidindex regeneration time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The macroinstruction performs preliminary generation of control indexes within its execution flow, calculating and storing indexes in advance during the same instruction cycle as the data rearrangement operation. This preliminary action ensures index availability is maintained while eliminating the need for separate regeneration or retrieval operations, reducing time loss.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If multiple instructions are used to generate control indexes, then flexible data rearrangement is achieved, but processing speed decreases

Engineering Contradiction:

Improvedata rearrangement flexibilityVSAvoidprocessing speed

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent merges control index generation with packed data rearrangement in a single macroinstruction, maintaining flexible data rearrangement capabilities through integrated control logic. The unified execution unit processes both operations simultaneously, achieving the same adaptability as multi-instruction sequences but at higher processing speed due to reduced instruction overhead and single-cycle execution.

Inventive Principle:

Principle #5Merging (Combining)
