Any changes taken to the computer system are mainly for the goal that gets the highest working performance at the lowest cost. Computer performance evaluation methods can be classed into three areas, namely, Performance Measurement, Analytical Performance Modeling, and Simulation Performance Modeling. The directly performance measurement method can provide more precise and more real performance evaluation results than the other methods. 　　By the help of traces, we can get the memory allocation, executing flow and memory reference of a program that can make us more understand the behavior of the data movement between the processor and the memory hierarchies system. On the other hand, traces can be taken to be the input of a deterministic simulation performance model. The trace-driven simulation model is a very popular technique for the evaluation of computer performance and the study of storage hierarchies system. 　　Most traces collection techniques did not reduce the trace length. Typically, it consumes a considerable disk space to store the traces. Real-time Trace Collection and Compression Technique, not only can collection the traces when the taget system is executing, but also can provide a real-time compression technique to solve the storage requirement problem.
