The current issue is a StallF is required to halt the icache from getting an updated PCF. However if the dmemory is the reason for a stall it is possible for the icache stall to hold the d memory request continuously causing d memory to repeatedly read from memory. This keeps StallF high and the icache FSM is never allowed to complete. |
