Post interrupts - computer architecture:

Post interrupts

  • Exact interrupts
  • examine interrupt bit on entering WB
  • Longer latency

Handle immediately

  •   interrupt may take place in order different from sequential CPU
  •   not completely precise
  •   May cause implementation headaches!

Other complications

  •   odd bits of state (for instance :CC)
  •   early-writes (for instance auto increment)
  •   out-of-order execution
  •   dynamic scheduling
  •   instruction buffers and prefetch logic
