Processors, methods, and systems with a configurable spatial accelerator

Systems, methods, and apparatuses relating to a configurable spatial accelerator are described. In one embodiment, a processor includes a synchronizer circuit coupled between an interconnect network of a first tile and an interconnect network of a second tile and comprising storage to store data to be sent between the interconnect network of the first tile and the interconnect network of the second tile, the synchronizer circuit to convert the data from the storage between a first voltage or a first frequency of the first tile and a second voltage or a second frequency of the second tile to generate converted data, and send the converted data between the interconnect network of the first tile and the interconnect network of the second tile
