Abstract: Methods and apparatus are disclosed for programming reconfigurable logic devices such as FPGAs in a multi-tenant server environment. In one example, a computing host includes one or more processors configured to execute a supervisor process and two or more user processes and a single FPGA integrated circuit configured into a plurality of partitions. The partitions include a host logic partition that is accessible only to the supervisor process executing on the computing host, and two or more accelerator partitions. Each of the accelerator partitions is configured to include a virtual debug unit with a logic analyzer that collects logic signals generated by logic within the respective accelerator partition and sends debug data indicating values of the logic signals to one of the user processes. In some examples, the host logic partitions and/or the accelerator partitions can be independently reprogrammed of each other within their respective portions of the single FPGA.

Abstract: The following description is directed to a logic repository service. In one example, a method of a logic repository service can include receiving a first request to generate configuration data for configurable hardware using a specification for application logic of the configurable hardware. The method can include generating the configuration data for the configurable hardware. The configuration data can include data for implementing the application logic. The method can include encrypting the configuration data to generate encrypted configuration data. The method can include signing the encrypted configuration data using a private key. The method can include transmitting the signed encrypted configuration data in response to the request.

Abstract: The following description is directed to a configurable logic platform. In one example, a configurable logic platform includes host logic and a plurality of reconfigurable logic regions. Each reconfigurable region can include hardware that is configurable to implement an application logic design. The host logic can be used for separately encapsulating each of the reconfigurable logic regions. The host logic can include a plurality of data path functions where each data path function can include a layer for formatting data transfers between a host interface and the application logic of a corresponding reconfigurable logic region. The host interface can be configured to apportion bandwidth of the data transfers generated by the application logic of the respective reconfigurable logic regions.

Abstract: A multi-tenant environment is described with configurable hardware logic (e.g., a Field Programmable Gate Array (FPGA)) positioned on a host server computer. For communicating with the configurable hardware logic, an intermediate host integrated circuit (IC) is positioned between the configurable hardware logic and virtual machines executing on the host server computer. The host IC can include management functionality and mapping functionality to map requests between the configurable hardware logic and the virtual machines. Shared peripherals can be located either on the host IC or the configurable hardware logic. The host IC can apportion resources amongst the different configurable hardware logics to ensure that no one customer can over consume resources.

Abstract: The following description is directed to a configurable logic platform. In one example, a configurable logic platform includes host logic and a reconfigurable logic region. The reconfigurable logic region can include logic blocks that are configurable to implement application logic. The host logic can be used for encapsulating the reconfigurable logic region. The host logic can include a host interface for communicating with a processor. The host logic can include a management function accessible via the host interface. The management function can be adapted to cause the reconfigurable logic region to be configured with the application logic in response to an authorized request from the host interface. The host logic can include a data path function accessible via the host interface. The data path function can include a layer for formatting data transfers between the host interface and the application logic.

Abstract: In a multi-tenant environment, separate virtual machines can be used for configuring and operating different subsets of programmable integrated circuits, such as a Field Programmable Gate Array (FPGA). The programmable integrated circuits can communicate directly with each other within a subset, but cannot communicate between subsets. Generally, all of the subsets of programmable ICs are within a same host server computer within the multi-tenant environment, and are sandboxed or otherwise isolated from each other so that multiple customers can share the resources of the host server computer without knowledge or interference with other customers.
