If you decide to include register scoreboarding, the cost *in hardware*
is extremely small --- basically negligible. {at least in MOS and
perhaps E/D-GaAs.} For a worked example, have a look at
Glenn Hinton et al, "A Register Scoreboarding Mechanism",
IEEE ISSCC digest, Feb 1988, pp. 270-1.
(The mechanism described is that implemented in Intel's embedded-
controller RISC cpu, the 960. Note the nine.)
