Abstract: The present disclosure is directed to 3-D stacked architecture for Programmable Fabrics and Central Processing Units (CPUs). The 3-D stacked orientation enables reconfigurability of the fabric, and allows the fabric to function using coarse-grained and fine-grained acceleration for offloading CPU processing. Additionally, the programmable fabric may be able to function to interface with multiple other compute chiplet components in the 3-D stacked orientation. This enables multiple compute components to communicate without the need for offloading the data communications between the compute chiplets.

Abstract: Processors may be enhanced by embedding programmable logic devices, such as field-programmable gate arrays. For instance, an application-specific integrated circuit device may include main fixed function circuitry operable to perform a main fixed function of the application-specific integrated circuit device. The application-specific integrated circuit also includes a support processor that performs operations outside of the main fixed function of the application-specific integrated circuit device, wherein the support processor comprises an embedded programmable fabric to provide programmable flexibility to application-specific integrated circuit device.

Abstract: In one embodiment, a method includes receiving a read request from a first caching agent, determining whether a directory entry associated with the memory location indicates that the information is not present in a remote caching agent, and if so, transmitting the information from the memory location to the first caching agent before snoop processing with respect to the read request is completed. Other embodiments are described and claimed.

Abstract: Embodiments of the invention describe a cache coherency protocol that eliminates the need for ordering between message classes and also eliminates home tracker preallocation. Embodiments of the invention describe a less complex conflict detection and resolution mechanism (at the home agent) without any performance degradation in form of bandwidth or latency compared to prior art solutions. Embodiments of the invention describe a home agent that may receive request messages, e.g., data ownership request messages and data request messages, which include issuance data indicating an order of the respective message issued. Said home agent may determine whether an early or late conflict exists based, at least in part, on a received conflict response message and the issuance data of a most recent completed transaction.
