A performance model for integrated layer processing

Abstract [en]

Integrated Layer Processing is an implementation technique for data manipulation functions in communication protocols. The purpose of this technique is to increase communication performance. It reduces the number of memory accesses and thus relieves the memory bandwidth bottleneck. Integrated Layer Processing can however, in some situations, substantially increase the number of memory accesses, and therefore instead reduce performance. The main reason is contention for processor registers. We present a performance model that captures the memory behavior of data manipulation functions for both integrated and sequential implementations. By comparing the model to measurements of real and synthetic data manipulation functions, we show that the model accurately predicts the performance. The model can be used to assess whether an integrated implementation will perform better or worse than a sequential implementation. The situations where integration would reduce performance can then be avoided without spending a lot of effort on a more complex integrated implementation.
