[comp.arch] Scoreboarding HW is simple

mark@mips.COM (Mark G. Johnson) (05/11/89)

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.)

As a matter of fact, I do!  Please stop doing whatever job you have now and
republish DTACK Ground.  Life has been so booorrring without it.
