14 years agoO3PCU: Split loads and stores that cross cache line boundaries.
Timothy M. Jones [Fri, 12 Feb 2010 19:53:20 +0000 (19:53 +0000)]
O3PCU: Split loads and stores that cross cache line boundaries.

When each load or store is sent to the LSQ, we check whether it will cross a
cache line boundary and, if so, split it in two. This creates two TLB
translations and two memory requests. Care has to be taken if the first
packet of a split load is sent but the second blocks the cache. Similarly,
for a store, if the first packet cannot be sent, we must store the second
one somewhere to retry later.

This modifies the LSQSenderState class to record both packets in a split
load or store.

Finally, a new const variable, HasUnalignedMemAcc, is added to each ISA
to indicate whether unaligned memory accesses are allowed. This is used
throughout the changed code so that compiler can optimise away code dealing
with split requests for ISAs that don't need them.

14 years agoBaseDynInst: Make the TLB translation timing instead of atomic.
Timothy M. Jones [Fri, 12 Feb 2010 19:53:19 +0000 (19:53 +0000)]
BaseDynInst: Make the TLB translation timing instead of atomic.

This initiates a timing translation and passes the read or write on to the
processor before waiting for it to finish. Once the translation is finished,
the instruction's state is updated via the 'finish' function. A new
DataTranslation class is created to handle this.

The idea is taken from the implementation of timing translations in
TimingSimpleCPU by Gabe Black. This patch also separates out the timing
translations from this CPU and uses the new DataTranslation class.
