摘要：
A system and method of avoiding loss of memory trace data, including monitoring a first-in-first-out (FIFO) buffer to determine if the FIFO buffer has overflowed due to memory access, determining whether an overflow of the FIFO buffer is acceptable, changing an operating mode of a target system if overflow of the FIFO buffer is unacceptable to avoid FIFO buffer overflow, and collecting memory trace data on the memory accesses.
