Figure 4-1: System Architecture

The DSP has a default core voltage of 1.5V. Refer to section 3.6.1 for more information about changing the core voltage while the DSP is running. The voltage of the DSP’s peripheral interface is 3.3V.

A 20 MHz oscillator supplies the input clock to the DSP. The speed at which the core and peripherals operate is determined by the configuration of the multiplier select switch (SW2) at reset. (See section 4.3.4.) By default, the DSP core runs at 300 MHz and the peripheral interface runs at 120 MHz. A 32.768 kHz crystal supplies the Real Time Clock (RTC) inputs of the DSP

The EZ-KIT Lite board can be configured to boot in all of the possible ADSP- 21535 boot modes. For information about configuring the boot mode, see section 4.3.3.
