You can choose PC-based analog data-acquisition boards that incorporate DSPs or Intel-based processors, but you can also rely on the host PC for computational tasks.
Undoubtedly, today's near-gigahertz-rate Pentium-class chips have the power to take on the processing chores required for most PC-based analog data-acquisition tasks. But considerations beyond raw power may dictate whether you can afford to allocate host processing power to the computations your data-acquisition applications require. You'll want to consider host-processor overhead, of course, but you'll also want to consider the amount of bus traffic your application will develop as well as your ...
