Virtually indexed, physically tagged caches


  • Medium speed:
    • lookup in parallel with address translation
    • tag comparison after address translation
  • No homonym problem
  • Potential synonym problem
  • More bits per tag (cannot leave off set-number bits)
    • increases area, latency, power consumption
  • Used on most modern architectures for L1 cache
