2.6.5 Data Abort
|
|
||||||
There are three Abort Model in ARM arch.
|
|
||||||
|
|
||||||
Early Abort Model: used in some ARMv3 and earlier implementations. In this
|
|
||||||
model, base register wirteback occurred for LDC,LDM,STC,STM instructions, and
|
|
||||||
the base register was unchanged for all other instructions. (oldest)
|
|
||||||
|
|
||||||
Base Restored Abort Model: If a Data Abort occurs in an instruction which
|
|
||||||
specifies base register writeback, the value in the base register is
|
|
||||||
unchanged. (strongarm, xscale)
|
|
||||||
|
|
||||||
Base Updated Abort Model: If a Data Abort occurs in an instruction which
|
|
||||||
specifies base register writeback, the base register writeback still occurs.

|
|
||||||
2.4 Register1:control register
|
|
||||||
L(bit 6): in some ARMv3 and earlier implementations, the abort model of the
|
|
||||||
processor could be configured:
|
|
||||||
0=early Abort Model Selected(now obsolete)
|
|
||||||
1=Late Abort Model selceted(same as Base Updated Abort Model)
|
|
||||||
|
|
||||||
on later processors, this bit reads as 1 and ignores writes.
|
|
||||||
-------------------------------------------------------------
|
|
||||||
So, if lateabtSig=1, then it means Late Abort Model(Base Updated Abort Model)
|

if lateabtSig=0, then it means Base Restored Abort Model
