Concluding remarks
Manycore processors

There is a clear distinction between multicore and manycore processors that goes beyond the number of cores. Multicore processors use a shared memory model with a single address space and complex cache hierarchies.

Manycores use a distributed memory model, with SRAM blocks close to the computing cores, most often interconnected with 2D grids.

It is this spatial distribution of compute-SRAM blocks that allows for a significant increase in the number of cores, with one or more levels of 2D grids.

For high-performance mobile and embedded applications, the results are mixed. Approaches targeting very low power consumption, such as Epiphany, are used in 16- and 64-core versions as coprocessors in Adapteva's Parallela cards, which target the high-performance, low-power mobile and embedded market. However, the 1,024-core...
