213. In this big-endian computation, register
nn holds –n, and register
data points to the octabyte following the given bytes αn – 1 . . . α1α0 in memory (with αn – 1 first). The constants
aa = #
bb = #
339bcf6530180c06 correspond to matrices A and B, found by computing the remainders xk mod p(x) for 72 ≤ k < 80.
A similar method finishes the job, with no auxiliary table needed:
aaa = #
bbb = #
ffooo = #
ff00. . .
The Books of the Big-Endians have been long forbidden.
