Solution Overview
Problem
Existing computing systems face challenges in optimizing the space and time required for configuring devices due to redundant write operations and inefficient storage of configuration data, which can be exacerbated in small systems with limited resources.
Innovation Solution
A method involving the optimization of write operation sequences by identifying redundant operations, reordering tuples to minimize distances, using indexed values and addresses, and applying encoding techniques such as ULEB and Huffman encoding to reduce the size of configuration data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant write operations are included in the configuration sequence, then the device configuration is complete and correct, but the configuration time and number of operations increase
Solution Approach 1:
The patent extracts and removes redundant write operations from the configuration sequence. By analyzing the configuration data to identify operations that write the same value to the same register multiple times, the system removes these redundant operations while preserving the necessary configuration steps, thereby reducing configuration time without compromising correctness
Solution Approach 2:
The patent performs preliminary analysis of the configuration sequence before execution to identify and mark redundant operations. This preliminary processing allows the system to optimize the configuration sequence in advance, eliminating unnecessary operations before they are executed, thus reducing overall configuration time
2Reliability
If configuration data is stored with full values and addresses, then the configuration is accurate and complete, but the storage space required increases
Solution Approach 1:
The patent applies local quality by using different representations for different parts of the configuration data. Frequently occurring register addresses and values are encoded using fewer bits (e.g., 8-bit indices) while maintaining full precision where needed. This localized optimization reduces overall storage requirements while preserving configuration accuracy
Solution Approach 2:
The patent changes the parameter representation from full-width values to compressed formats. By transforming register addresses and data values into compressed representations (such as ULEB128 encoding or indexed references), the system significantly reduces the storage space required while maintaining the ability to accurately reconstruct and apply the configuration
3Productivity
If the configuration sequence is optimized by reordering operations, then the execution time is reduced, but the complexity of processing increases
Solution Approach 1:
The patent performs preliminary reordering of the configuration sequence to group related operations together and optimize execution efficiency. By analyzing dependencies and reorganizing operations before execution, the system reduces total configuration time while keeping the optimization logic centralized in the configuration generation phase rather than adding complexity to the execution phase

AI summary
Presented herein are systems and methods for configuring devices with write operations. One or more processors can identify a first sequence of write operations to configure a device. Each write operation in the first sequence of write operations can identify a set of a value and an address to which to write the value. The one or more processors can determine one or more distances between a set of the value and the address of a write operation and at least one other set of the value and the address of one or more other write operations in the first sequence of write operations. The one or more processors can generate a second sequence of write operations based at least on the one or more distances. The one or more processors can cause the device to be configured using the second sequence of write operations.
