Hardware and software don't matter

The typical DSP design process has three basic elements: Algorithm design, hardware design, and software design. Similarly, most DSP engineers think of themselves as belonging to one of three groups: Algorithm designers, hardware designers, or software designers.

This division of labor causes problems. For one thing, it creates a "thought gap" between the engineering groups: Algorithm designers rarely understand how the hardware works, the hardware designers rarely understand how software development works, and so on. In addition, each group tends to limit its thinking to its own area of specialization. For example, software designers don't want to worry about hardware design; they just want a hardware platform that works. This narrow thinking hinders the groups from aiding each other. Perhaps worst of all, each group uses different tools, languages, etc. As a result, miscommunication between the groups is common.
