The e300 has a new data cache queue sharing extension that
allows the two burst-write queues in the bus unit to be used
interchangeably for cache replacements and snoop pushes. Thus,
the data cache can support two outstanding cache replacements
or two outstanding snoop push operations on the bus at any given
time.
The e300 supports a new instruction cache block touch instruction
that facilitates preloading the instruction cache before locking; the
G2_LE core requires speculatively fetching instructions before
locking the instruction cache.
For the e300, a new transaction can complete an address tenure
when the previous transaction has been granted the data bus; for
the G2_LE, a new transaction must wait until the previous data
tenure has completed before completing its address tenure.
PowerPC little-endian will not be supported in the e300 core,
although true little-endian will be fully supported.
drtry and drtrymode will no longer be supported on the e300 and
future versions.
The eciwx and ecowx instruction pair will not be supported on the
e300 core. These are optional instructions in the PowerPC
architecture.
