DSP VS. CUSTOMIZED HARDWARE

It is also noteworthy that a DSP implementation may not be as effective as customized hardware. One obvious benefit is that customized hardware can be designed to perform better than a generalized DSP. For example, in systems that need a high sampling rate, customized hardware may be the best approach. For large volume applications, it may be less expensive to use customized hardware instead of a DSP approach. An application with fewer requirements often does not need the full functionality of a DSP. Therefore, the full operations of the DSP may be too costly for an application with a narrow range of functions. Notwithstanding, the long lead times for the design and manufacturing of customized hardware usually translates ...
