Summary: A well written document. There are a few review comments below that
the authors should consider.

Major issues: None

Minor issues:

According to statistical tests (BigCrush in TestU01
<> and AdaptiveCrush
<>) the
 quality of the outputs of TinyMT seems pretty good,

SB> It would be useful to the reader to specify  "pretty good"


   The TinyMT32 PRNG initialization depends, among other things, on a
   parameter set -- namely (mat1, mat2, tmat) --

SB> These probably need a few words  of explanation on introduction.


   static void tinymt32_next_state (tinymt32_t * s);
SB> I assume that this notation is good C, but
SB> type space star space name does not seem common.
SB> This may confuse some readers. One more often
SB> sees one of the spaces omitted.


Nits/editorial comments:

   This specialisation aims at having a simple-to-use and deterministic
   PRNG, as explained below.

SB> I assume that "deterministic PRNG" is a term of the art, but the
SB> it sounds like an oxymoron to the uninitiated. Perhaps a word
SB> or two would clarify.
