Optimization of Stateful Hardware Acceleration in Hybrid Architectures

In many computing domains, hardware accelerators can improve throughput and lower power consumption, instead of executing functionally equivalent software on the general purpose micro-processors cores. While hardware accelerators often are stateless, network processing exemplifies the need for stateful hardware acceleration. The packet oriented streaming nature of current networks enables data processing as soon as packets arrive rather than when the data of the whole network flow is available. Due to the concurrence of many flows, an accelerator must maintain and switch contexts between many states of the various accelerated streams embodied in the flows, which increases overhead associated with acceleration.
