Description
Descriptor Destination ID. These bits define which Port to route the request to, if it is a
‘hit’ based on the other settings in this register.
000: Port 0 (GLIU0 = GLIU; GLIU1 = GLIU.)
001: Port 1 (GLIU0 = GLMC; GLIU1 = Interface to GLIU0.)
010: Port 2 (GLIU0 = Interface to GLIU1; GLIU1 = VP.)
011: Port 3 (GLIU0 = CPU Core; GLIU1 = GLCP.)
100: Port 4 (GLIU0 = DC; GLIU1 = GLPCI.)
101: Port 5 (GLIU0 = GP; GLIU1 = VIP.)
110: Port 6 (GLIU0 = Not Used; GLIU1 = SB.)
111: Port 7 (GLIU0 = Not Used; GLIU1 = Not Used.)
Compare Bizzaro Flag.
0: Consider only transactions whose Bizzaro flag is low as a potentially valid address hit.
1: Consider only transactions whose Bizzaro flag is high as a potentially valid address
Physical Memory Address 2s Comp Offset. 2s complement offset that is added to
physical address on a hit.
Physical Memory Address Base. These bits form the matching value against which the
masked value of the physical address, bits [31:12] are directly compared. If a match is
found, then a “hit’ is declared, depending on the setting of the Bizzaro flag comparator.
Physical Memory Address Mask. These bits are used to mask address bits [31:12] for
the purposes of this ‘hit’ detection.
A low Bizzaro flag indicates a normal transaction cycle such as a memory or I/O.
hit. A high Bizzaro flag indicates a ‘special’ transaction, such as a PCI Shutdown or
Halt cycle.
