RapiTaskZero is a specialized software analysis tool designed to provide deep insight into an application's scheduling behavior, particularly for critical software systems. It automatically collects comprehensive information during program execution without requiring modifications to the target system, offering a "zero-footprint" approach. This data is then presented in a clear, actionable format, allowing users to follow the sequence of events that occurred during a test run. The software provides a detailed timeline of tasks, along with a wealth of charts and statistics, enabling in-depth analysis of system scheduling behavior. A key capability of RapiTaskZero is its ability to easily locate and help fix rare timing events, such as priority inversions, which can be notoriously difficult to detect. By tracking system tasks throughout execution, it visualizes these events, for example, by color-coding tasks according to priority. Furthermore, the tool assists in identifying bottlenecks within applications by allowing users to view the CPU utilization of each task over time. This helps prevent system slowdowns or failures caused by missed timing deadlines. Unlike many vendor-specific scheduling visualization tools, RapiTaskZero offers a common framework for understanding scheduling behavior across different Real-Time Operating Systems (RTOSs), reducing the need to learn multiple tools. It also uniquely allows for the analysis of scheduling behavior in third-party libraries or other software components for which source code access is unavailable, by analyzing branch traces and disassembly to produce results.

Features & Benefits

• Scheduling Analysis & Insight
  • Automatically collects information during program execution, presenting this data so users can follow the events that occurred in the test run, providing a timeline of tasks, charts, and statistics for in-depth analysis.
• Rare Timing Event Detection
  • Helps find and fix rare timing events such as priority inversions by following system tasks throughout execution, with easy visualization (e.g., color coding by priority).
• Bottleneck Identification
  • Assists in identifying bottlenecks by allowing users to view CPU utilization of each task, preventing system slowdowns or failures due to missed deadlines.
• RTOS Agnostic Comparison
  • Enables understanding of system scheduling behavior through a common framework, compatible with various RTOSs, reducing learning time for new tools.
• Library Analysis (No Source Code)
  • Allows analysis of third-party libraries or software without source code access, as it analyzes branch traces and disassembly to produce results.
