Abstract: Using a high-level language (HLL) callable library for multiple instances of a core includes detecting, using computer hardware, a reference to an HLL library for a core within an HLL application, determining, using the computer hardware, a plurality of instances of the core by detecting function calls within the HLL application correlated to each of the plurality of instances of the core, and generating, using the computer hardware, interface code within the HLL application for each of the plurality of instances of the core using the HLL library. An executable version of the HLL application is generated, using the computer hardware, wherein the interface code for each of the plurality of instances of the core is bound to the respective instance of the core. The function calls can specify different parameterization files corresponding to the plurality of instances of the core.

Abstract: Creating a high-level language (HLL) callable library for a hardware core can include automatically querying, using computer hardware, a metadata description of a core to determine a plurality of available ports of the core, automatically determining, using the computer hardware, an argument of a first function specified in a header file corresponding to the core, mapping, using the computer hardware, the argument to a first port of the plurality of available ports, and automatically generating and storing, using the computer hardware, an HLL library specifying a mapping of the argument to the first port of the core. The HLL library is configured for inclusion with a user application during compilation.

Abstract: Implementing an application within a heterogeneous device can include receiving an application specifying a plurality of hardware accelerators and having a plurality of sections corresponding to different subsystems of the heterogeneous device, wherein the plurality of sections are specified using different programming models. Compiling each section based on the programming model of the section and the subsystem of the heterogeneous device corresponding to the section into an accelerator representation. Linking the accelerator representations based on a platform of the heterogeneous device, generating a hardware implementation of the application for the heterogeneous device based on the linked accelerator implementations, and automatically generating program code configured to control one or more of the plurality of hardware accelerators of the hardware implementation.

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.
