Abstract
Methodologies and architectures are provided for inter-thread sharing of data in a general purpose register (GPR) of a multiprocessor apparatus. The data sharing is performed by a graphics processing unit (GPU) having at least one processing cluster including a plurality of processing cores (PCs) configured for parallel operation. Each PC of a cluster is configured to utilize a dedicated portion of the GPR. The GPU further includes a shared memory for the cluster, and a memory read/write hub coupled to the GPR and shared memory, the hub including a crossbar switch. A PC executes a move data instruction, including operands referencing a destination portion of the GPR and a source portion assigned to the PC, to retrieve data from the source portion. The memory read/write hub writes the data, via the crossbar switch, to the destination portion of the GPR without first writing the data to the shared memory.
