Search latency from command to SRAM access cycle is 4 for a single device in the table with TLSZ = 00. In addition, SSV and
SSF shift further to the right for different values of HLAT as specified in Table 13-2.
13.2
68-bit Search on Tables Configured as ×68 Using up to Eight CYNSE70032 Devices
The hardware diagram of the Search subsystem of eight devices is shown in Figure 13-4. The following are the parameters
programmed into the eight devices.
• First seven devices (devices 0–6): CFG = 00000000, TLSZ = 01, HLAT = 010, LRAM = 0, and LDEV = 0.
• Eighth device (device 7): CFG = 00000000, TLSZ = 01, HLAT = 010, LRAM = 1, and LDEV = 1.
Note
. All eight devices must be programmed with the same values for TLSZ and HLAT. Only the last device in the table (device
number 7 in this case) must be programmed with LRAM = 1 and LDEV = 1. All other upstream devices (devices 0 through 6 in
this case) must be programmed with LRAM = 0 and LDEV = 0.
Figure 13-5 shows the timing diagram for a Search command in the 68-bit-configured table of eight devices for device number 0.
Figure 13-6 shows the timing diagram for a Search command in the 68-bit-configured table of eight devices for device number 1.
Figure 13-7 shows the timing diagram for a Search command in the 68-bit-configured table of eight devices for device number 7
(the last device in this specific table). For these timing diagrams four 68-bit searches are performed sequentially. HIT/MISS
assumptions were made as shown below in Table 13-3.
