Latest Patents
One of Junshan Xu's latest patents is titled "Graph Based Code Performance Analysis." This patent describes techniques for analyzing the performance of software through graph-based methods. The implementations involve instrumenting code by adding annotations that do not alter the functionality of the code but provide valuable call tracking information during execution. This information can be used to generate a call graph, illustrating the relationships between functions in the code. The call graph can be analyzed to develop recommendations for code coverage, impact information, and optimization strategies.
Another significant patent is "Coverage of Call Graphs Based on Paths and Sequences." This invention involves a program that collects call stack data from test cases executed on an application. The program generates call graphs that represent the functions executed during these test cases. It also identifies short paths and sequences within the call graphs, allowing for targeted testing of modifications made to functions in the application.
