Handling Interrupts:

Precise interrupts (sequential semantics)

  • Complete instructions before the offending instructions

o   Force trap instruction into IF

o   Squash (effects of) instructions after

o   Save PC (& next PC with delayed branches)

  • Must handle simultaneous interrupts

o   ID - illegal/privileged instruction

o   EX - arithmetic exception

o   IF, M - memory access ( misaligned, page fault protection)
