Adaptable protocol processing architectures can offer quality-of-service (QoS) while improving energy efficiency and resource utilization. However, a key condition for adaptable architectures to support QoS is that, the latency required for processor adaptation does not result in violating packet processing delay bound. Moreover, adaptation latency must not cause packets to accumulate until memory becomes full and packets are dropped. In this paper, we present an elastic management scheme for agile adaptable multi-core protocol processing architecture to facilitate processor adaptation when QoS has to be maintained. The proposed management scheme encompasses a set of reconfigurable finite state machines (FSMs) and each is dimensioned to associate single processing element (PE). During processor adaptation, the needed FSMs can rapidly be clustered to provide the control needed for the newly adapted structure. We use a real-life application to demonstrate how our proposed management scheme supports maintaining QoS during processor adaptation. We also quantify the time needed for processor adaptation as well as the reduction in energy, latency and area achieved when using our scheme.
