Which type of memory is provided in DSP processor?

The low cost fixed-point DSP typically processes 16 bit data and contain 32 bit registers. They have various RAM and ROM configurations, a 16 bit I/O bus, and serial ports. The mid-range processor operates between 27-50 Mhz, with 16-32 bit floating point operations and 16-24 bit fixed point operations.

What is on chip peripherals in DSP?

The on-chip peripherals include a 10/100-Mbit/s Ethernet MAC (media access controller), and a VLYNQ interface. VLYNQ is a full-duplex serial communications interface that enables the extension of an internal bus segment to one or more external physical devices.

What are the desirable features of DSP processor?

The general DSP is designed and optimized for applications such as digital filtering, correlation, convolution, and FFT. In addition to these applications, the special DSP has features that are optimized for unique applications such as audio processing, compression, echo cancellation, and adaptive filtering.

What are the advantages of DSP processor compared to microprocessor?

A DSP is a specialized microprocessor used to perform calculations efficiently on digitized signals that are converted from the analog domain. One of the big advantages of DSP is the programmability of the processor, which allows important system parameters to be changed easily to accommodate the application.
