Abstract

A design structure including universal peripheral processor architecture on an integrated circuit (IC) includes a first data bus and a second data bus communicating with first and second ternary content addressable memory (TCAM) devices configured as state machines. First and second processors are coupled to the first bus interface logic and the second bus interface logic. First and second data storage devices communicate with the first and second processors and are coupled to the first and second data buses and communicate with each other. The TCAM devices are configured as state machines and are coupled to and adapted to interface with the processors, the data storage devices, and the bus interface logic using predefined protocols.
