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.) -- -- Mark Johnson MIPS Computer Systems, 930 E.
