Abstract: A cross-domain device includes a memory with a shared memory region. The device further includes a first interface to couple to a first device over a first interconnect, where the first device implements a first domain, and includes a second interface to couple to a second device over a second interconnect, where the second device implements a second domain, and the first domain is independent of the second domain. The cross-domain device is to create a buffer in the shared memory region to allow writes by a first software module in the first domain and reads by a second software module in the second domain, and use the buffer to implement a memory-based communication link between the first software module and the second software module.

Abstract: Systems, methods, and apparatuses for direct memory access instruction set architecture support for flexible dense compute using a reconfigurable spatial array are described. In one embodiment, a processor includes a first type of hardware processor core that includes a two-dimensional grid of compute circuits, a memory, and a direct memory access circuit coupled to the memory and the two-dimensional grid of compute circuits; and a second different type of hardware processor core that includes a decoder circuit to decode a single instruction into a decoded single instruction, the single instruction including a first field to identify a base address of two-dimensional data in the memory, a second field to identify a number of elements in each one-dimensional array of the two-dimensional data, a third field to identify a number of one-dimensional arrays of the two-dimensional data, a fourth field to identify an operation to be performed by the two-dimensional grid of compute circuits, and a fifth field to indicate the direct memory access circuit is to move the two-dimensional data indicated by the first field, the second field, and the third field into the two-dimensional grid of compute circuits and the two-dimensional grid of compute circuits is to perform the operation on the two-dimensional data according to the fourth field, and an execution circuit to execute the decoded single instruction according to the fields.

Abstract: Embodiments of apparatuses, methods, and systems for scheduling tasks to hardware threads are described. In an embodiment, a processor includes a multiple hardware threads and a task manager. The task manager is to issue a task to a hardware thread. The task manager includes a hardware task queue to store a descriptor for the task. The descriptor is to include a field to store a value to indicate whether the task is a single task, a collection of iterative tasks, and a linked list of tasks.
