Solution Overview

Problem

Existing data processing systems face inefficiencies when handling input tensors that do not meet predetermined dimensions, leading to increased power consumption, resource usage, and reduced performance due to the need for additional processing and memory operations to pad or revert to less efficient implementations.

Innovation Solution

The system employs instruction decoding circuitry to handle out-of-bounds memory accesses by writing data from a source storage to a target storage, overwriting preloaded values in one portion while omitting out-of-bounds data in another portion, ensuring the target storage has the desired number of elements without additional padding steps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the system copies the input tensor in memory and manipulates the copied tensor to achieve the required dimension, then the dimension requirement is met, but additional processing and memory resources are required leading to increased power consumption and reduced performance

Engineering Contradiction:
Improvedimension requirementVSAvoidperformance
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The target storage is preloaded with padding values before the data transfer operation. This preliminary action eliminates the need for subsequent padding operations, as the correct dimension is already established in the target storage. The system simply needs to transfer valid data to overwrite the preloaded padding values, avoiding additional processing steps and improving performance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent separates the padding value storage from the data transfer operation. By preloading padding values into the target storage, the system extracts the padding function from the data transfer path, allowing the data transfer to proceed efficiently without dimensional manipulation overhead.

Inventive Principle:
Principle #2Taking out (Extraction)

2Manufacturing precision

If the system copies the input tensor in memory and manipulates the copied tensor to achieve the required dimension, then the dimension requirement is met, but additional memory resources are required

Engineering Contradiction:
Improvedimension requirementVSAvoidmemory resources
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

Padding values are preloaded into the target storage before the data transfer operation. This eliminates the need to allocate additional memory for padding operations, as the target storage is already prepared with the correct dimension and values. The system only needs to transfer valid data to the appropriate locations.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the system reverts to another implementation of the operation using scalar processing and additional control flow, then the operation can be performed on insufficiently padded input, but less efficient implementations are used leading to increased power consumption and reduced performance

Engineering Contradiction:
Improveinput dimension flexibilityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The target storage is preloaded with padding values before the data transfer operation, enabling efficient vector processing regardless of the input tensor's initial dimension. This preliminary preparation allows the system to maintain efficient implementation while accepting input tensors of varying dimensions, as the padding structure is already in place and does not require runtime scalar processing.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If the system reverts to another implementation of the operation using scalar processing and additional control flow, then the operation can be performed on insufficiently padded input, but less efficient implementations are used leading to reduced performance

Engineering Contradiction:
Improveinput dimension flexibilityVSAvoidperformance
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

By preloading padding values into the target storage before the data transfer operation, the system enables efficient vector processing for input tensors of any dimension. The padding structure is prepared in advance, allowing the data transfer to proceed using efficient vector instructions rather than falling back to slower scalar processing with control flow, thus maintaining high performance while accepting flexible input dimensions.

Inventive Principle:
Principle #10Preliminary action
