Software Development for Embedded Multi-core Systems

Chapter 7. Case Study: Data Decomposition

Key Points

• Performance analysis of a GUI application must be performed carefully, oftentimes requiring use of special steps and tools’ features.

• Determining the location to insert threading is based upon a number of factors including frequency of execution, source code modifications, and threading overhead.

• When implementing threading, manually inspect the code to determine variables that need to be shared and private. Use the thread verification tool for difficult to find threading issues.

The threading development cycle (TDC) provides a useful step-by-step process that can be applied to a threading project. This chapter employs the process on a real application where the concurrent work is found via data ...
