- * Implements a simple scoreboard to track which registers are ready.
- * This class assumes that the fp registers start, index wise, right after
- * the integer registers. The misc. registers start, index wise, right after
- * the fp registers.
- * @todo: Fix up handling of the zero register in case the decoder does not
- * automatically make insts that write the zero register into nops.
