A method of designing an integrated circuit using a general purpose programming language can include identifying a number of instances of each class allocated in a programmatic design implemented using the general purpose programming language and modeling the global memory of the programmatic design. A data flow between the modeled global memory and instructions of the programmatic design which access object fields can be determined and access to the modeled global memory can be scheduled. The programmatic design can be translated into a hardware description of the integrated circuit using the modeled global memory, the data flow, and the scheduled memory access.

Method of transforming software language constructs to functional hardware equivalents

A method of processing a general-purpose, high level language program to determine a hardware representation of the program can include compiling the general-purpose, high level language program to generate a language independent model () and identifying data input to each component specified in the language independent model to determine a latency for each component (). The components of the language independent model can be annotated for generation of control signals such that each component is activated when both control and valid data arrive at the component (). Each component also can be annotated with an output latency derived from a latency of a control signal for the component and a latency determined from execution of the component itself ().

Scheduling hardware generated by high level language compilation to preserve functionality of source code design implementations

A method of processing a general-purpose, high level language program to determine a hardware representation of the program can include compiling the general-purpose, high level language program to generate a language independent model (, and). The language independent model can be scheduled such that each component is activated when both control and valid data arrive at the component (). An interface structure specifying a hardware interface through which devices external to the language independent model interact with a physical implementation of the language independent model can be defined and included in the language independent model ().

A method of designing an integrated circuit using a general purpose programming language can include identifying () a number of instances of each class allocated in a programmatic design implemented using the general purpose programming language and modeling () the global memory of the programmatic design. A data flow between the modeled global memory and instructions of the programmatic design which access object fields can be determined () and access to the modeled global memory can be scheduled (). The programmatic design can be translated () into a hardware description of the integrated circuit using the modeled global memory, the data flow, and the scheduled memory access.
