The nature of an FPGA allows for straightforward implementation of many digital
processing structures that require only relatively small signal delay such as the one
illustrated in Figure 2-4. For larger delay values a dedicated RAM device will be
required.
The use of FPGA design allows the user to review the design at multiple levels of
abstraction for maximum learning potential and possibly a more intuitive design process.
The personal computer has always been the dominant platform for running audio
processing software on, mainly because of the standardised and well-established
hardware and operating systems. However, as embedded technology matures, audio
processing may be able to move away from the potentially unreliable standard computer
and move towards a form of dedicated, reconfigurable platform that can do, or ‘be’
anything you want it to.
