Using general-purpose processors instead of dedicated DSPs for DSP-intensive applications has some advantages, as well as some pitfalls. General-purpose [MuPs are a viable option in some system designs.
As DSP becomes ubiquitous in both PCs and embedded applications, many product designers must decide how to best implement signal-processing functions in their systems. In many cases, designers have to choose between using a dedicated DSP or using a [Mu]P or [Mu]C already present in the design. For a system designer, choosing whether to implement DSP on a general-purpose [Mu]P greatly depends on the application. Cost, power consumption, development tools, software, ...
