摘要: In one embodiment, a processor includes decode circuitry and memory offload circuitry. The decode circuitry decodes an instruction to perform a direct memory access (DMA) operation, which includes an opcode and one or more fields. The opcode indicates a type of DMA operation to be performed. The one or more fields indicate a destination memory region and one or more data operands. The memory offload circuitry offloads the instruction from an execution pipeline and performs the DMA operation.

摘要: A graph processing core includes a plurality of processing pipelines and an interrupt controller unit. Each processing pipeline executes one or more threads and includes, for each thread, a register indicating a currently executing program counter vector and another register indicating an interrupt or exception handler vector. The interrupt controller unit may receive interrupt or exception notifications from the processing pipelines, determine a handler vector based on the notification and a set of registers of the interrupt controller unit, and transmit the handler vector to the processing pipeline that issued the interrupt or exception notification. Further, the issuing pipeline may receive the handler vector from the interrupt controller unit, write a value in the first register into the second register, write the handler vector into the first register, and invoke an interrupt or exception hander based on the value written into the first register.
