Photonic Many-Core Architecture Study
Source: University of California
Several recent device technology developments have been fundamentally changing the microprocessor architecture design space. These developments include photonic interconnects, feature size reduction, 3D fabrication, and aggressive energy management. These technologies create a large parameter space of possible future architectures. The focus of this paper and research effort is to demonstrate a set of efficient architecture parameters that yield good performance for DoD relevant applications. To achieve this goal, two key challenges must be addressed. First, an expressive logical abstraction of the hardware needs to be developed. This abstraction or machine model can then be parameterized given hardware requirements and capabilities. Second, detailed modeling at the application level has to be performed.
