An example is ARM systems including an ETM component that supports data tracing. You connect an external trace probe, usually via JTAG, to receive the trace events. This technique usually uses read/write and control-flow state for reconstruction. This has the advantage of not requiring a recording from the beginning to reconstruct since you can correctly work backward from the final state, but requires higher data bandwidth and storage.
