Functional Description
The following subsections contain command (CMD) and DQ bus (command and databus), database entry, arbitration logic,
pipeline and SRAM control, and full logic descriptions.
4.1
CMD Bus and DQ Bus
CMD[8:0] carries the CMD and its associated parameter. DQ[67:0] is used for data transfer to and from the database entries,
which comprise a data and a mask field that are organized as data and mask arrays. The DQ bus carries the Search data (of the
data and mask arrays and internal registers) during the Search command as well as the address and data during Read and/or
Write operations. The DQ bus can also carry the address information for the flow-through accesses to the external SRAMs and/or
SSRAMs.
4.2
Database Entry (Data Array and Mask Array)
Each database entry comprises a data and a mask field. The resultant value of the entry is “1,” “0,” or “X (don’t care),” depending
on the value in the data and mask bits. The on-chip priority encoder selects the first matching entry in the database that is nearest
to location 0.
4.3
Arbitration Logic
When multiple search engines are cascaded to create large databases, the data being searched is presented to all search engines
simultaneously in the cascaded system. If multiple matches occur within the cascaded devices, arbitration logic on the search
engines will enable the winning device (with a matching entry that is closest to address 0 of the cascaded database) to drive the
SRAM bus.
