Abstract: Application-specific tailoring and reuse of a platform for a target integrated circuit may include determining, using a processor, a plurality of unused interfaces of the platform and determining, using the processor, connectivity of a circuit block to be coupled to the platform within the target integrated circuit.

Abstract: In an example implementation, a method is provided for compiling an HLL source file including function calls to one or more hardware accelerated functions. Function calls in the HLL source file to hardware accelerated functions are identified and grouped into a plurality of subsets for exclusive implementation in programmable logic resources. Sets of configuration data are generated for configuration of the programmable logic resources to implement hardware accelerated functions for the respective subsets of function calls. An interface manager is generated and the identified function calls are replaced with interface code configured to communicate with the interface manager. The interface manager manages configuration of the programmable logic resources to switch between the sets of configuration data to implement hardware accelerated functions for different ones of the subsets.

Abstract: Implementing a system-on-chip (SOC) design specified as a high level programming language (HLL) application may include querying, using a computer, a platform description to determine an available interface of a platform for a target integrated circuit and generating, using the computer, hardware for a function of the HLL application marked for hardware acceleration and hardware coupling the marked function with the available interface of the platform. Implementing the SOC design may also include modifying, using the computer, the HLL application with program code configured to access the generated hardware for the marked function and building, using the computer, the hardware and the software of the SOC design.

Abstract: In an example implementation, a method is provided for compiling an HLL source file. The HLL source file checked for function calls to a set of hardware-accelerated functions having hardware implementations specified in a hardware library. For each HLL function call to a hardware-accelerated function, a circuit design is retrieved from the hardware library. The circuit design specifies a hardware implementation of the hardware-accelerated function. HLL interface code configured to communicate with the hardware implementation of the hardware-accelerated function is also generated. The HLL function call to the hardware-accelerated function in the HLL source file is replaced with the generated interface code. The HLL source file is compiled to generate a program executable on a processor of a programmable IC. Configuration data is generated that implements the retrieved circuit designs on the programmable circuitry of the programmable IC.

Abstract: A method is provided for compiling an HLL program. A command is input that indicates a set of HLL source files to be compiled and a set of functions in the HLL source files that are to be implemented on programmable circuitry of a programmable IC. For a source file including one of the set of functions, a respective netlist is generated from HLL code of each of the set of functions included therein. Interface code is also generated for communication with the netlist. HLL code of the set of functions in the HLL source file is replaced with the generated interface code. Each HLL source file is compiled to produce a respective object file. The object files are linked to generate a program executable on the programmable IC. A configuration data stream is generated that implements each generated netlist on the programmable IC.
