Device Compatibility

The DM641/DM640 device is a code-compatible member of the C6000

 DSP platform.

The C64x

 DSP generation of devices has a diverse and powerful set of peripherals. The common peripheral

set and pin-compatibility that the DM641 and DM640 devices offer lead to easier system designs and faster

time to market.

The DM640 device is a sub-set of the DM641 device and does not support an HPI peripheral or a second Video

Port (VP1) peripheral. Table 1−3 identifies the peripherals that are available on the DM641 and DM640

devices.
