The hardware diagram of the Search subsystem of eight devices is shown in
Figure 10-30
. The following are parameters
programmed into the eight devices.
First seven devices (devices 0–6): CFG = 01010101, TLSZ = 01, HLAT = 010, LRAM = 0, and LDEV = 0.
Eighth device (device 7): CFG = 01010101, TLSZ = 01, HLAT = 010, LRAM = 1, and LDEV = 1.
Note
. All eight devices must be programmed with the same value of TLSZ and HLAT. Only the last device in the table must be
programmed with LRAM = 1 and LDEV = 1 (device number 7 in this case). All other upstream devices must be programmed with
LRAM = 0 and LDEV = 0 (devices 0 through 6 in this case).
Figure 10-31
shows the timing diagram for a Search command in the 136-bit-configured table of eight devices for device 0.
Figure 10-32
shows the timing diagram for a Search command in the 136-bit-configured table consisting of eight devices for
device number 1.
Figure 10-33
shows the timing diagram for a Search command in the 136-bit configured table consisting of
eight devices for device number 7 (the last device in this specific table). For these timing diagrams, four 136-bit searches are
performed sequentially, and the following Hit/Miss assumptions were made (see
Table 10-20
).
