The logical 288-bit SEARCH operation is shown in
Figure 68, page 93. The entire table of 288-bit en-
tries is compared to a 288-bit word K that is pre-
sented on the DQ Bus in Cycles A, B, C, and D of
the command using the GMR and local mask bits.
The GMR is the 288-bit word specified by the two
pairs of GMRs selected by the GMR Indexes in the
command
s Cycles A and C. The 288-bit word K
that is presented on the DQ Bus in Cycles A, B, C,
and D of the command is compared with each en-
try in the table starting at location
0.
The first
matching entry
s location address,
L,
is the win-
ning address that is driven as part of the SRAM
address on SADR[23:0] lines (see SRAM AD-
DRESSING, page 128).
Note:
The matching address is always going to be
location
0
in a four-entry page for a 288-bit
SEARCH (two LSBs of the matching index will be
'00').
The SEARCH command is a pipelined operation
and executes at one-fourth the rate of the frequen-
cy of CLK2X for 288-bit searches in x288-config-
ured tables. The latency of SADR, CE_L, ALE_L,
WE_L, SSV, and SSF from the 288-bit SEARCH
command (measured in CLK cycles) from the
CLK2X cycle that contains the C and D Cycles is
shown in Table 42, page 93.
The latency of a SEARCH from command to
SRAM access cycle is 4 for only a single device in
the table and TLSZ = 00. In addition, SSV and SSF
shift further to the right for different values of
HLAT, as specified in Table 43, page 93.
