The following two errors are corrected in the version posted on this site.

  • The text of the paper that appears in the proceedings refers to Table 6.3 in Section 6.3. Table 5 should be referred to in place of Table 6.3.
  • Table 3 in the paper that appears in the proceedings shows an under-estimate for the forward L2Map in the block-grain and ideal block-grain designs. Each forward L2Map entry requires a 20-bit tag, and as a result, each forward L2Map entry would be 38 bits in size as opposed to 18 bits.
