TODO: aggiungere riferimento alla configurazione single core

The nu+ manycore is a parametrizable regular mesh Network on Chip (NoC) of configurable tile, developed by CeRICT in the framework of the MANGO FETHPC project. The main objective of nu+ is to enable resource-efficient HPC based on special-purpose customized hardware. Our aim is to build an application-driven architecture to achieve the best hardware/software configuration for any data-parallel kernel. Specialized data-parallel accelerators have been known to provide higher efficiency than general-purpose processors for codes with significant amounts of regular data-level parallelism (DLP). However every parallel kernel has its own ideal configuration.

Each nu+ tile has the same basic components, it provides a configurable GPU-like open-source soft-core meant to be used as a configurable FPGA overlay. This HPC-oriented accelerator merges the SIMT paradigm with vector processor model. Furthermore, each tile has a Cache Controller and a Directory Controller, those components handle data coherence between different cores in different tiles.

TODO: manca synchronization_core (ed io_interface?)

TODO: aggiungere figura architettura single core

User design can set an high number of parameter for every need, such as:

  • NoC topology and Tile number.
  • Threads per core number. Each thread has a different PC, so one core can executes as many program as many threads it has.
  • Hardware lanes per thread. Each thread can be a vector operation (here called hardware lane).
  • Register file size (scalar and vector).
  • L1 and L2 cache size and way number.

There are all the hardware main section. Each of them covers important aspects of the hardware.
