Runtime Optimization of a Tracking Algorithm
The customer faced a significant challenge with the excessively long runtime of their tracking algorithm. The C++ algorithm ran on the Texas Instruments fixed-point DSP C6424.
Initially, the source code was analyzed for its optimization potential, which resulted in an extensive to-do list. Subsequently, runtime profiling was added to the source code, enabling a detailed runtime analysis.
The algorithm was optimized over several weeks, employing the following techniques:
- Loop optimization
- Memory optimization
- More efficient sorting algorithms
- Targeted use of multiple parallel processing units of the DSP
- All while considering the numerics and tracking performance
The runtime was thus initially reduced to approximately 20% of the original runtime. This enabled the customer to further develop the tracking algorithm. During this period, d.stream ensured sufficient free CPU capacity through further optimizations.
Result for the Customer:
- Feared hardware redesign avoided
- Costs saved
- Performance enhanced
- Algorithm could be further improved by the customer
