3. Characteristics of manycores

As with multicores, a manycore is a parallel architecture integrated into a single circuit. All the problems associated with parallel architectures are therefore covered. We won't repeat the basic concepts presented in [H 1 088] : "Introduction to parallelism and parallel architectures".

As previously stated, manycores are not simply a continuation of multicores. If they were, there would be no need to change terminology. There are a number of architectural parameters to consider. In this section, we review these parameters, taking examples with...
