Re: [Gems-users] Question about getAddress, .... in GEMS

[Rakesh Komuravelli <komurav1@xxxxxxxxxxxx>]

No,

getLogicalAddress() returns the virtual address of the request passed by simics to ruby.

getPhysicalAddress() returns the physical address of the request.
getAddress() returns the line address of the request.

To verify, look at 

ruby/simics/SimicsProcessor.C: memoryTransactionToCacheMsg(memory_transaction_t) (CacheMsg created)

and

ruby/system/Sequencer.C: issueRequest(CacheMsg) (m_address modified)

Thanks,

Rakesh

Hi,

There are three methods in cacheMSG of Gems. I have question about them and if possible please answer my questions.

I think that getPhysicalAddress and getLogicalAddress methods in cacheMSG return physical and logical address of a block where requested variable places in this block. For example, if variable X exists in block 1000, request1.getLogicalAddress() returns 1000 instead of X address (request1 accesses to X). Is it true?

Thanks for your answer in advance.
