Amazing Trace

This paper describes the implementation of an execution history, called "Amazing Trace", that entails decoding and analyzing a recorded instruction trace, and in particular the design and implementation of a data structure which can encapsulate the entire state of the target system, including memory and registers, over time, and to do this efficiently because the trace buffer can contain data for hundreds of thousands of instructions. The Amazing Trace is also integrated in the IAR Embedded Workbench C-SPYDebugger, such that the history can be traversed both forwards and backwards while inspecting the full target state through the normal debugger windows
