Significant, probably, but also hellishly complicated to do anything
useful with. Risky, too; microcode tends to allow things like gating
more than one internal register onto an internal data bus at the same
time. And probably strictly Harvard, rather than von Neumann.
And very, very processor-rev-specific.
