Engineering Scope
Local feature extraction and data reduction were developed to solve specific engineering problems in low-power projects. The work starts from the customer's existing design and business requirements, develops features, aggregation or compression, and compares the energy increased by calculation and reduced transmission; the algorithm code, parameters, data comparison and end-to-end energy consumption records are delivered according to the agreed module.
Check input with baseline
Check the original data samples, business output, error tolerance, calculation and communication baseline, and clarify the scope of measurement and modification.
Implementation and adaptation
Develop features, aggregations, or compressions, compare computational gains to reduced energy in transmissions, and document trade-offs and dependencies.
Target environment joint debugging
Verify data loss, event omission, processing delay and communication savings, and confirm business behavior after parameter changes.
Document and record delivery
Provide algorithm code, parameters, data comparison and end-to-end energy consumption records, and explain the version, construction or usage method.
Project Workflow
- Input confirmation: original data samples, business output, error tolerance, calculation and communication baseline.
- How to implement: Develop features, aggregations, or compressions that compare the increased energy in the calculation versus the decreased energy in the transmission.
- Stage review: Verify data loss, missed events, processing delays, and communication savings.
- Project delivery: algorithm code, parameters, data comparison and end-to-end energy consumption records.
Design Conditions and Functional Limits
It needs to include comparison of calculation time, memory access and transmission process. You can't just look at the number of output bytes, but also confirm whether the business information is retained.
Special services take the agreed module as the implementation boundary. When hardware modifications, third-party agreements, overall platforms or external tests are involved, the interfaces, workload and responsibilities are confirmed separately, and local modifications are not directly used as conclusions on the performance of the complete device.
Project Inputs
- Raw data samples, business output, error tolerance, computing and communication baselines.
- Existing prototypes and reproducible problems, or new project functionality and power consumption targets.
- Modified design, source code and third-party dependencies are allowed; functionality and compatibility need to be maintained.
- Delivery list, target environment, sample scope, project milestones and acceptance methods.
Delivery and Acceptance
| Delivery content | Check method |
|---|---|
| Algorithm code, parameters, data comparison and end-to-end energy consumption records | Check the editability, version, usage instructions and dependencies by file list. |
| Implementation verification | Verify data loss, event omissions, processing delays and communication savings, and retain corresponding working conditions and results. |
| Comparison of functions and power consumption | Fixed applicable hardware, software, battery, temperature and business cycles, accounting for changes in conditions and their impact. |
| Reproduction and follow-up maintenance | Provide build or run steps, known limitations, parameter ranges, and uncovered cases. |
Frequently Asked Questions
How to compare the overall energy consumption of different compression methods?+
It needs to include comparison of calculation time, memory access and transmission process. You can't just look at the number of output bytes, but also confirm whether the business information is retained.
What information do I need to prepare before starting the project?+
This work focuses on original data samples, business output, error tolerance, computing and communication baselines. When the data is incomplete, first determine the scope that needs supplementary testing or sorting out, and then proceed to implementation.
Can it be implemented together with the complete device development project?+
It can be used as a work package in the overall project, or it can be implemented separately for existing products. It is necessary to explain the interfaces with other modules, versions and final machine verification responsibilities.
