Comparison of DSP with General Purpose Processor

Take an Example of FIR filtering both by a General Purpose Processor as well as DSP




An FIR (Finite Impulse Response filter) is represented as shown in the following figure.

The output of the filter is a linear combination of the present and past values of the input. It has several advantages such as:
- Linear Phase.
- Stability.
- Improved Computational Time.
