TIE - The Fast Path to High-Performance Embedded SOC Processing
Optimize SOC Performance Using Memory Tuning and System Simulation
Xtensa Xplorer helps designers analyze and select configurations to meet speed/area goals. The Xtensa Xplorer design environment provides automatic estimates of the area impact of designer-defined instructions.

Performance charts visually compare different configurations. In the chart below, two configurations are compared and the difference in the number of cycles and the number of cache misses is significant.

The Cache Xplorer automatically profiles code and visualizes results across a range of cache configuration options. The chart below clearly shows the performance impact of varying cache sizes.
