What is DSP in cars?
1 Answers
Car DSP is an audio processor, specifically an audio enhancement processor that can enhance surround stereo effects and other special audio effects by modifying the audio signal. DSP processors generally have the following main features: 1. Separate program and data spaces, allowing simultaneous access to instructions and data. 2. On-chip fast RAM, usually accessible through 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. While DSP amplifiers possess the functions of other amplifiers, they can also attenuate overlapping frequencies caused by the car environment, boost frequencies that are weakened by the environment, and adjust the distance between each speaker in the car and the human ear.
