Product Attributes

Overview

The DSP56374 is designed to support a multitude of digital signal processing applications requiring a lot of horsepower in a small package. While the DSP56374 is designed with flexibility and thus is versatile in the types of applications it can support, it does include a powerful set of audio features, including various built-in audio peripherals and embedded software designed to meet the needs of both consumer and automotive audio applications.

The DSP56374 provides a wealth of audio processing functions including an operating system, various equalization algorithms, compression, signal generator, tone control, fade/balance, level meter/spectrum analyzer, and many more. The DSP56374 also supports various matrix decoders and sound field processing algorithms.

The DSP56374 uses the high performance, single-clock-per-cycle DSP56300 core family of programmable CMOS digital signal processors (DSPs) combined with the audio signal processing capability of the Symphony®.sup>TM DSP family. This design provides a two-fold performance increase over NXP®.’s popular DSP56000 core family of DSPs while retaining code compatibility.

Significant architectural enhancements include a barrel shifter, 24-bit addressing, patch module, and direct memory access (DMA). The DSP56374 is available in either a 52-pin or 80-pin TQFP at 150 million instructions per second (MIPS) using an internal 150 MHz clock at 1.25 V.
