RATS: Reactive Architectures
Abstract
This project had two goals: To build an emulation prototype board for a tiled architecture and to demonstrate the utility of a global inter-chip free-space photonic interconnection fabric for polymorphous computer architectures (PCA). The free-space optics part of the project focused on two critical issues to validate the use of ultra-high-capacity global free- space interconnection fabrics for polymorphous computing architectures. These issues fell into the categories of interface issues and internal switch issues. The VCSEL-based free-space optical system was shown to be tolerant of misalignments, although electrical packaging problems prevented a full-performance demonstration. The optical links for the free-space system were demonstrated at 2.5 Gbps each with an inter-chip distance of about 10 cm. The project successfully demonstrated an optical inter-board fiber-based interconnect and intra-board free-space interconnect. The project also developed a prototype board that was demonstrated with an emulator of a tiled architecture.
