Image of NXP Semiconductor's DSP56303 24-bit Digital Signal Processor NXP Semiconductor's DSP56303 is intended for use in telecommunication applications such as multi-line voice/data/fax processing, video conferencing, audio applications, control, and general digital signal processing.

The DSP56303 is a member of the DSP56300 core family of programmable CMOS Digital Signal Processors (DSPs). This family uses a high performance, single clock cycle per instruction engine. While retaining code compatibility it provides a twofold performance increase over NXP's popular DSP56000 core family.

Significant architectural enhancements to the DSP56300 core family include a barrel shifter, 24-bit addressing, instruction cache, and DMA. The DSP56303 offers 100 MMACS using an internal 100 MHz clock at 3.0 - 3.6 volts. The DSP56300 core family offers a high level of performance in speed and power provided by its rich instruction set and low power dissipation for wireless, telecommunications, and multimedia products.
