Hi all:
My mips is 24k core series, and I have some questions when I using mtc0/mfc0.
1. no matter what "spacing" in the execution-hazard or
instruction-hazard, is it enough to use "ehb" and "JALR.HB" once?
2.
below is excerpted from the spec.
producer consumer
hazard on spacing
MTC0 -> Interrupted instruction
Status 2
MTC0 ->Load/Store affected by new state
StatusER 3
MTC0 -> Coprocessor instruction affected by new state StatusCU 4
MTC0 -> Instruction fetch seeing the new value
EntryHiASID 10
Are there any example which can tell me what does
" Interrupted instruction"
"Load/Store affected by new state"
"Coprocessor instruction affected by new state"
" Instruction fetch seeing the new value"
mean?

Thanks for your help in advance,
