[Gems-users] Instruction Flow (contd...)

[arrvindh shriraman <arrvindh_shriraman@xxxxxxxxx>]

(1) Does OPAL drive SIMICS
In other words. Does OPAL actually execute the
instructions and then advance the SIMICS processor
cycle
(1 cycle is 1 pipeline cycle)

(2) Does SIMICS drive OPAL ?
OPAL obtains instruction to be executed and memory
events from SIMICS

Mike Marty specified in his reply that you advance
simics cycle  to execute multiple instructions ? Why
do you do this ? And won't this affect correctness, If
a memory load is returned and OPAL doesn't see this
immediately because SIMICS was advanced multiple
instructions

Thanks
