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: 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.

Abstract: Access control is provided for peer-to-peer communication between a source peripheral device and a destination peripheral device without going through a host device. The access control mechanism can allow or block a request for a transaction to go out via a port of the source peripheral device to the destination peripheral device by comparing an attribute associated with the transaction with a filter attribute stored in memory. Embodiments of the disclosed technologies can allow programming of different filter attributes for different tenants in a multi-tenant environment.

Abstract: 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.

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: Reference data is one type of data that the video accelerator may frequently be read from external memory. In various examples, the video accelerator can adaptively select inter-prediction modes based on the bandwidth to external memory that is available at any point in time. The video accelerator can determine the amount of bandwidth that is available, and when the bandwidth is insufficient for obtaining reference data for all possible inter-prediction modes, the video accelerator can select an inter-prediction mode based on the size of the reference window associated with the inter-prediction mode, the size being within an amount of data that can be read with the available bandwidth. The video accelerator can then obtain a reference window from external memory, and perform prediction using the selected inter-prediction mode and the reference window.

Abstract: A controller is configured to transmit a broadcast write request on at least one bus. The broadcast write request includes an address and a value. A first logic module determines that the broadcast write request is targeting the first logic module. The first logic module stores the value at a first addressed register specified by the register address. The second logic module determines that the broadcast write request is targeting the second logic module. The second logic module stores the value at a second addressed register specified by the register address. The first and second logic modules are connected to the at least one bus.
