What is a DSP in cars?
1 Answers
Car DSP is an audio processor, specifically a sound enhancement processor, designed to enhance special sound effects such as surround stereo and perform certain modifications to audio signals. Compared to ordinary amplifiers, car DSPs significantly outperform in many ways. While possessing all the functions of other amplifiers, DSP amplifiers can also attenuate overlapping frequencies caused by the in-car environment. Below are the main features generally found in DSP processors: 1. Separate program and data spaces, allowing simultaneous access to instructions and data. 2. On-chip fast RAM, typically accessible via independent data buses in two blocks simultaneously. 3. Hardware support for low-overhead or no-overhead loops and jumps. 4. Fast interrupt handling and hardware I/O support.
