The final stage downloads the compiled (or assembled) and linked program into the
target hardware (such as EVM) and brings it to a real-time operation. Thus the real-
time debugging process is primarily constrained to debugging the I/O timing structure
and testing the long-term stability of the algorithm. Once the algorithm is running, we
can again `tune' the parameters of the systems in a real-time environment.
3.8 Experiments of Fixed-Point Implementations
The purposes of experiments in this section are to learn input quantization effects and to
determine the proper fixed-point representation for a DSP system.
