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.

Logic repository service using encrypted configuration data

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 receiving a second request to download the configuration data to a host server computer comprising the configurable hardware. The method can include transmitting the configuration data to the host server computer in response to the second request so that the configurable hardware is configured with the host logic and the application logic.

Logic repository service

The following description is directed to a logic repository service supporting adaptable host logic. 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. The method can include selecting a particular host logic shell from a group of host logic shells. The particular host logic shell can be used to encapsulate the application logic when the configurable hardware is configured. Configuration data for the configurable hardware can be generated. The configuration data can include data for implementing the application logic and at least a portion of the particular host logic shell. The method can include receiving a second request to download the configuration data to a host server computer comprising the configurable hardware. The configuration data can be transmitted to the host server computer in response to the second request.

Disclosed are techniques regarding aspects of implementing client configurable logic within a computer system. The computer system can be a cloud infrastructure. The techniques can include associating signature information with the client configurable logic for various purposes.

Client configurable hardware logic and corresponding signature

Methods and apparatus are disclosed for securely erasing partitions of reconfigurable logic devices such as FPGAs in a multi-tenant server environment. In one example, a method of securely erasing an FPGA includes identifying one partition of previously-programmed resources in the FPGA, erasing the identified partition by storing new values in memory or storage elements of the identified partition, and storing new values in memory or storage elements of additional external resources electrically connected to the integrated circuit and associated with the identified partition. Thus, other partitions and subsequent users of the identified partition are prevented from accessing the securely erased data. A configuration circuit, accessible by a host computer via DMA, can be programmed into the FPGA reconfigurable logic for performing the disclosed erasing operations.

Controlling access to previously-stored logic in a reconfigurable logic device

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.

Configurable logic platform with multiple reconfigurable regions

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.

Extracting debug information from FPGAs in multi-tenant environments

Client configurable hardware logic and corresponding hardware clock metadata

Disclosed are techniques regarding aspects of implementing client configurable logic within a computer system. The computer system can be a cloud infrastructure. The techniques can include providing an identifier in response to configuring client configurable logic within the computer system.

Interception of identifier indicative of client configurable hardware logic and configuration data

A licensing server object generator identifies a plurality of servers that can be used to obtain a license for accessing a feature of an application. The licensing server object generator determines, for the identified servers, network addresses and utilizes these network addresses to generate a plurality of data objects. Each data object specifies a subset of the network addresses for the servers. The licensing server object generator makes these data objects available to enable use of the data objects to obtain the license.
