Application specific IP placement for on-chip distributed architectures

Abstract

In this paper we approach the performance aspects of MPSoC platforms, from the point of view of IP placement with the focus on Network-on-Chip(NoC). Proper IP placement is important for several time-dependent applications such as video and voice where traffic must be delivered on time in order to operate properly. Proper placement of IPs can lower the traffic congestion, improve overall execution time and power consumption. We have suggested a new criteria for the prioritization of IPs regarding placement. Based on that criteria, we implemented an algorithm for IP placement.The running example is represented by mapping of H.264 encoder application on a NoC mesh. Allocation of processing elements on the platform, topology and communication mechanism are the main topics described here.
