Description
BTB_Branch Predictor. The predictor state for the branch.
00: Strongly not taken.
01: Weakly not taken.
10: Weakly taken.
11: Strongly taken.
BTB Target Address. The 32-bit linear branch target address.
Description
Reserved. Write as read.
Return Stack Pointer Access (Read Only). Data in RS_DATA (MSR 0000110Bh[31:0])
is the Return Stack Target Address or Return Stack Pointer. After a read/write of the
Return Stack Data register, the Return Stack Index (RS_INDX, bits [2:0]) auto-incre-
ments. When the value of the index reaches 7h, it remains at this value for two read/write
cycles. For the second read/write, RS_PA is a 1 so that the Return Stack Pointer can be
read or write.
0: Data is Return Stack Target Address.
1: Data is Return Stack Pointer.
Reserved. Write as read.
Return Stack Index. Contains the address used to access the eight Return Stack entries
and the Return Stack Pointer. This register auto-increments when the Return Stack Data
register is read/write.
