• Description: Network Database Coprocessor
• Manufacturer: Cypress Semiconductor

Table 7-15. Result Register 0 for Search Operation
Processor ID[4:0]. The processor ID from the command descriptor is identified here.
Context ID[4:0]. The context ID from the command descriptor is identified here.
Hit. The hit flag indicates whether the search was successful.
Done. This field indicates that the command has been processed. The done bit is cleared when the Result Register 0 is Read
by the network processor. A new command can be initiated by the network processor through this descriptor after the done bit
has cleared.
Table 7-16. Result Register 1 (Search Result Bit in Data Field = 0)
Table 7-17. Result Register 1 (Search Result Bit in Data Field = 1)
7.3.7
For the search operation where the SSRAM is connected to the network processor (see Figure 13-1), the Result Register 0 carries
the search response (see Table 7-18) and result register 1 is unused.
Table 7-18. Search Response in Result Register 0 (type I)
Processor ID[4:0]. The processor ID set in the command descriptor is set here.
Context ID[4:0]. The context ID set in the command descriptor is set here.
Hit. The hit flag indicates whether the search was successful.
Done. This field indicates that the command has been processed. The done bit is cleared when the Result Register 0 is Read
by the network processor. A new command can be initiated by the network processor through this descriptor after the done bit
has cleared.
