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. |
|||

chap2 The System Control Coprocessor CP15 |
|||
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 |
|||
because the ARMs which skyeye simulates are all belonged to ARMv4, |
|||
so I think MMUReg[1]'s bit 6 should always be 1 |
