DSP56303
24-Bit Digital Signal Processor
The DSP56303 is a member of the DSP56300 core family of programmable CMOS DSPs. Significant architectural
features of 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 rich instruction set and low power dissipation, as well as increasing levels of speed and power to enable
wireless, telecommunications, and multimedia products.
