Also, dedicated DSPs usually have better power efficiency, thus they are more suitable in portable devices such as mobile phones because of power consumption constraints. Most general-purpose microprocessors can also execute digital signal processing algorithms successfully, but may not be able to keep up with such processing continuously in real-time. The goal of a DSP is usually to measure, filter or compress continuous real-world analog signals. They are widely used in audio signal processing, telecommunications, digital image processing, radar, sonar and speech recognition systems, and in common consumer electronic devices such as mobile phones, disk drives and high-definition television (HDTV) products.
: 104–107 DSPs are fabricated on MOS integrated circuit chips.
The NeXTcube from 1990 had a Motorola 68040 (25 MHz) and a digital signal processor Motorola 56001 with 25 MHz which was directly accessible via an interface.Ī digital signal processor ( DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing.
