Is DSP still relevant?

Digital signal processing is used everywhere. DSP is used primarily in areas of audio signal, speech processing, RADAR, seismology, audio, SONAR, voice recognition, and some financial signals.

Why FPGA is better than DSP?

FPGAs offer a more native implementation for most DSP algorithms. Each task is allocated its own resources, and runs independently. It intuitively makes more sense to process each step of a continuously streaming signal processing chain in an assembly line-like process, with dedicated resources for each step.

How many types of DSP processors are available in the market?

Digital signal processors are available in two types fixed-point processors and floating-point processors.

Which is the architecture used in most DSP devices?

DSPs are usually optimized for streaming data and use special memory architectures that are able to fetch multiple data or instructions at the same time, such as the Harvard architecture or Modified von Neumann architecture, which use separate program and data memories (sometimes even concurrent access on multiple data ...
