Abstract

On-chip network design has become an increasingly important component of computer architecture. The Cell Broadband Engine's Element Interconnect Bus, with its four data rings and common command bus for end-to-end transaction control, interconnects more nodes than most commercial on-chip networks. To help understand on-chip network design and performance issues in the context of a commercial multicore chip, this article evaluates the EIB network using conventional latency and throughput characterization methods.
