As write through strategy is mentioned shouldnt we take SIMUALTANEOUS access formula for both read as well as write?
when we will use read as parallel access formula?
i think if we could have used simuletaneous access for read also...
will there be any need for cache memory? no na..
since read needs no modification we will not use simuletaneous access.
refer this :https://gateoverflow.in/76502/me-co-write-through
here for very same type of question they took ONLY Tm for read miss
please tell one concept as its diff everywhere
thanks in advance : )
thanks @Gokulnath, but could you please help me with this?
why simultaneous taken here instead of heirarchial?
it's hierarchical only check one more time we always don't consider the hierarchical for read because if question specify something for simultaneous or hierarchical then we consider according to that. If you will notice in first question which you have mentioned in question there is word like "memory hierarchy" so thats why we were using hierarchical access there but in second question its nothing mentioned like so if i go according to all previous year gate question by default we used hierarchical access.
Hope this help.
@Shubhgupta yes perfect!
so as in 2nd also they didn't mentioned anything so it should have been hierarchial only right?
