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 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.

generating a validated bitstream based on the application logic and the host logic, the validated bitstream specifying the configuration data for the FPGA;

receiving a second request to download the validated bitstream to a host server computer of the computing environment, the host server computer comprising a particular FPGA; and

transmitting the validated bitstream to the host server computer in response to the second request so that the particular FPGA is configured with the host logic and the application logic.

2. The method of claim 1, wherein the received hardware design comprises source code, and wherein generating the validated bitstream comprises synthesizing the received hardware design to generate a netlist compatible with the FPGA.
