An embodiment of a semiconductor package apparatus may include technology to manage one or more virtual graphic processor units, and co-schedule the one or more virtual graphic processor units based on both general processor instructions and graphics processor instructions. Other embodiments are disclosed and claimed.

Systems, apparatuses, and methods for implementing as part of a processor pipeline a reprogrammable execution unit capable of executing specialized instructions are disclosed. A processor includes one or more reprogrammable execution units which can be programmed to execute different types of customized instructions. When the processor loads a program for execution, the processor loads a bitfile associated with the program. The processor programs a reprogrammable execution unit with the bitfile so that the reprogrammable execution unit is capable of executing specialized instructions associated with the program. During execution, a dispatch unit dispatches the specialized instructions to the reprogrammable execution unit for execution. The results of other instructions, such as integer and floating point instructions, are available immediately to instructions executing on the reprogrammable execution unit since the reprogrammable execution unit shares the processor registers with the integer and floating point execution units.

A method includes receiving, by a level two (L2) controller, a first request for a cache line in a shared cache coherence state; mapping, by the L2 controller, the first request to a second request for a cache line in an exclusive cache coherence state; and responding, by the L2 controller, to the second request.

A reconfigurable compute fabric can include multiple nodes, and each node can include multiple tiles with respective processing and storage elements. A first tile in a first node can include a processor with a processor output and a first register network configured to receive information from the processor output and information from one or more of the multiple other tiles in the first node. In response to an output instruction and a delay instruction, the register network can provide an output signal to one of the multiple other tiles in the first node. Based on the output instruction, the output signal can include one or the other of the information from the processor output and the information from one or more of the multiple other tiles in the first node. A timing characteristic of the output signal can depend on the delay instruction.

A circuit for fast interrupt handling is disclosed. An apparatus includes a processor circuit having an execution pipeline and a table configured to store a plurality of pointers that correspond to interrupt routines stored in a memory circuit. The apparatus further includes an interrupt redirect circuit configured to receive a plurality of interrupt requests. The interrupt redirect circuit may select a first interrupt request among a plurality of interrupt requests of a first type. The interrupt redirect circuit retrieves a pointer from the table using information associated with the request. Using the pointer, the execution pipeline retrieves first program instruction from the memory circuit to execute a particular interrupt routine.
