Main-stream general-purpose microprocessors require a collection of high-performance interconnects to supply the necessary data movement. The trend of continued increase in core count has prompted designs of packet-switched network as a scalable solution for future-generation chips. However, the cost of scalability can be significant and especially hard to(More)
Continued device scaling enables microprocessors and other systems-on-chip (SoCs) to increase their performance, functionality, and hence, complexity. Simultaneously, relentless scaling, if uncompensated, degrades the performance and signal integrity of on-chip metal interconnects. These systems have therefore become increasingly communications-limited. The(More)
As microprocessor chips integrate a growing number of cores, the issue of interconnection becomes more important for overall system performance and efficiency. Compared to traditional distributed shared-memory architecture, chip-multiprocessors offer a different set of design constraints and opportunities. As a result, a conventional packet-relay(More)
With increasing core count, chip multiprocessors (CMP) require a high-performance interconnect fabric that is energy-efficient. Well-engineered transmission line-based communication systems offer an attractive solution, especially for CMPs with a moderate number of cores. While transmission lines have been used in a wide variety of purposes, there lack(More)
