There are many algorithms that can combine many low-res images into a single hi-res image.

I think that Silkypix just uses a newer and better hi-res algorithm than ACR.

But that's not what's going on at the raw converter stage to a HiRes raw file. The camera internally merges the subframes using a fixed algorithm (perhaps similar to what's discussed in the linked paper) and outputs an ordinary looking Bayer-style raw file, albeit a much larger one constructed from the subsampling of each normal-sized pixel position. The raw converters are not called upon to do anything different with one of these HiRes raws than they do with normal raws.
