At the algorithm level, a model does not contain timing information, either internally or externally. At this level, data is represented at the functional level where function is captured internally, but no external interface is modeled. The structure is not defined, and SW programmability is at the DSP primitive level (i.e. FFT, FIR, etc..) e.g. using Matlab.
Performance models mainly measure the time effects of the system such as throughput, latency, and utilization
