This paper introduces a task switch history visualization tool for ART-Linux. It is designed to develop real-time applications efficiently. It helps developers to confirm that their applications are executed periodically without modifying their applications and to find sources of problems. It consists of three parts, Record tool, Record server and Visualization tool and supports multi-processor (core) systems. The record tool reads a task switch history from ART-Linux kernel and writes it on a inter-processor shared memory. The record server provides gathered histories to the visualization tool. The visualization tool visualize histories and provides analysis functions.
