In the evolving sub-micron technology, importance of wire delays is growing, making it particularly attractive to use decentralized designs. A common form of decentralization adopted in processors is to partition the execution core into multiple clusters. Each cluster has a small instruction window, and a set of functional units. A number of algorithms have been proposed for distributing instructions among the clusters. The first part of this paper analyzes (Qualitatively as well as quantitatively) the effect of various hardware parameters such as the type of cluster interconnect, the fetch size, the cluster issue width, the cluster window size, and the number of clusters on the performance of different instruction distribution algorithms.
