debugging method for embedded systems is generally to cross-compile the program for a specific circuit board (target machine) through the integrated development environment on the PC (host machine, then, the program is downloaded to the target board through the JTAG, serial port, or network port of the target board. Therefore, in order to construct a learning environment for an embedded system, it is often

the throughput of the system in the network. The key difference between hard real time and soft real-time is that soft real-time can only provide real-time in statistical sense. For example, some applications require the system to ensure that an action is completed within a specified period of time in 95% cases, not necessarily 100%. Real-time is to complete the
