US Patent:

6513108, Jan 28, 2003

Filed:

Jun 29, 1998

Appl. No.:

09/106478

Inventors:

Darren Kerr - Palo Alto CA
Kenneth Michael Key - Raleigh NC
Michael L. Wright - Raleigh NC
William E. Jennings - Cary NC

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 1516

US Classification:

712 19, 712 21

Abstract:

A programmable processing engine processes transient data within an intermediate network station of a computer network. The engine comprises an array of processing elements symmetrically arrayed as rows and columns, and embedded between input and output buffer units with a plurality of interfaces from the array to an external memory. The external memory stores non-transient data organized within data structures, such as forwarding and routing tables, for use in processing the transient data. Each processing element contains an instruction memory that allows programming of the array to process the transient data as processing element stages of baseline or extended pipelines operating in parallel.
