SEARCH COMMAND
The M7020R (Silicon) Search Engine can be con-
figured in ten ways:
– 68-bit SEARCH on tables configured as x68
using one device
– 68-bit SEARCH on tables configured as x68
using up to 8 devices
– 68-bit SEARCH on tables configured as x68
using up to 31 devices
– 136-bit SEARCH on tables configured as
x136 using one device
– 136-bit SEARCH on tables configured as
x136 using up to 8 devices
– 136-bit SEARCH on tables configured as
x136 using up to 31 devices
– 272-bit SEARCH on tables configured as
x272 using one devices
– 272-bit SEARCH on tables configured as
x272 using up to 8 devices
– 272-bit SEARCH on tables configured as
x272 using up to 31 devices
– Mixed-sizes on tables configured with differ-
ent widths using an M7020R
68-bit Configuration with Single Device
The hardware diagram of the search subsystem of
a single device is shown in Figure 19. Figure 20,
page 38 shows the timing diagram for a SEARCH
operation in the 68-bit configuration (CFG =
00000000) for one set of parameters. This illustra-
tion assumes that the host ASIC has programmed
TLSZ to '00,' HLAT to '000,' LRAM to '1,' and LDEV
to '1' in the command register.
The following is the sequence of operations for a
single 68-bit SEARCH command.
–
Cycle A:
The host ASIC drives CMDV high and
applies the SEARCH command code ('10') on
CMD[1:0] signals. CMD[5:3] must be driven with
the index to the global mask register pair for use
in the SEARCH operation. CMD[8:7] signals
must be driven with the same bits that will be
driven on SADR[21:20] by this device if it has a
hit. DQ[67:0] must be driven with the 68-bit data
to be compared. The CMD[2] signal must be
driven to Logic '0.'
–
Cycle B:
The host ASIC continues to drive
CMDV high and applies the SEARCH command
('10') on CMD[1:0]. CMD[5:2] must be driven by
the index of the comparand register pair for stor-
ing the 136-bit word presented on the DQ Bus
during Cycles A and B. CMD[8:6] signals must
be driven with the index of the SSR that will be
used for storing the address of the matching en-
try and the Hit Flag (see SEARCH-Successful
Registers (SSR[0:7]), page 23). The DQ[67:0]
continues to carry the 68-bit data to be com-
pared.
Note:
In the 68-bit configuration, the host ASIC
must supply the same data on DQ[67:0] during
both Cycles A and B. The even and odd pair of
GMRs selected for the comparison must be pro-
grammed with the same value.
