SPEAR: Shape-shifting many-core
(The Loki many-core processor)

Project

This 5-year ERC funded project (SPEAR ref:306386) builds upon our experience of designing on-chip networks and previous work on our flexible many-core architecture (Loki). The aim is to investigate the design and implementation of massively-parallel single-chip architectures that place the network at the heart of their design. Our simple cores are far more deeply interconnected to each other than traditional designs, sharing some similarities to FPGAs. The network is also free to carry both instructions and data between cores allowing cores to be exploited using a variety of execution patterns. We are pursuing work both the architecture and circuit levels, together with the development of new compilation tools.

A test-chip containing more than 100 cores will be fabricated in 2015.
