The DM3xx is a DMSoC family from TI providing an ARM based platform for running Linux and other operating systems. It comes with special video input and output functionality plus often some video accelerators.

Comparison between Family members

The below table lists the major differences between those devices. There might be some more differences that are not listed below because they are not that important for typical use cases, e.g. in the area of low speed peripherals. Further all areas where there is nearly no difference were skipped in order to keep the focus on whats different.

**1: listed data might be inaccurate since its not an official product from TI; its only referenced in some documents but seems to be very close to DM355 (see e.g. spraau4 page 5)

**2: as of now no product page for the processor is known; the device is as of now only advertised as a component of the DMVA1 IP Camera Reference Design
