Inter-Thread Communication in Multi-Threaded Reconfigurable Coarse-Grain Arrays

A processor includes a compute fabric and a controller. The compute fabric includes an array of compute nodes and interconnects that configurably connect the compute nodes. The controller is configured to configure at least some of the compute nodes and interconnects in the compute fabric to execute specified code instructions, and to send to the compute fabric multiple threads that each executes the specified code instructions. A compute node among the compute nodes is configured to execute a code instruction for a first thread, and to transfer a result of the code instruction within the fabric, for use as an operand by a second thread, different from the first thread.
