The infinity2m series of chips are like the other Mstar/Sigmastar chips in that they have a Cortex A7 system with DDR memory integrated in a single package. The infinity2m chips are intended for recording the incoming streams from IP cameras. So instead of video encoders they have video decoders, instead of a camera interface they have display hardware and so on. Aside from the above points the big difference about these chips is that they include a second Cortex A7 core.
