5.4 Power-Down Control

The C64x+ Megamodule supports the ability to power-down various parts of the C64x+ Megamodule. The

power-down controller (PDC) of the C64x+ Megamodule can be used to power down L1P, the cache

control hardware, the CPU, and the entire C64x+ Megamodule. These power-down features can be used

to design systems for lower overall system power requirements.

NOTE

The C6472 does not support power-down modes for the L2 memory at this time.

More information on the power-down features of the C64x+ Megamodule can be found in the

TMS320C64x+ DSP Megamodule Reference Guide (literature number SPRU871).

5.5 Megamodule Resets

Table 5-5 shows the reset types supported on the C6472 device and they affect the resetting of the

Megamodule, either both globally or just locally.
