Abstract

A system, method and article of manufacture are provided for automatically generating libraries for use in distributing software components without requiring the software components to be completely. The system receives a behavioral description of the system components and determines the optimal required functionality between hardware and software and provides that functionality while varying the parameters (e.g. size or power) of the hardware and/or software. Thus, for instance, the hardware and the processors for the software can be formed on a reconfigurable logic device, each being no bigger than is necessary to form the desired functions. The codesign system outputs a description of the required processors, machine code to run on the processors, and a net list or register transfer level description of the necessary hardware. It is possible for the user to write some parts of the description of the system at register transfer level to give closer control over the operation of the system, and the user can specify the processor or processors to be used, and can change, for instance, the partitioner, compilers or speed estimators used in the codesign system. Since the library has the latest technology in dynamic widths, the libraries are flexible in their ability to store and dynamically update their components based on the characteristics of a resolved system.

Claims

1. A method for using a library map during the design of cores, comprising the steps of:

(a) determining a plurality of macros which specify an interface; and

(b) utilizing one of a plurality of libraries during the execution of each of macro;

(c) wherein each macro is capable of being executed utilizing different libraries.

2. A method as recited in claim 1, wherein the macros are executed on a co-processor which is capable of executing the macros utilizing different libraries.

3. A method as recited in claim 1, wherein the macros are compiled in a file.

4. A method as recited in claim 1, and further comprising defining a plurality of first variables in the macros with reference to variable widths;

defining a plurality of second variables in the macros without reference to variable widths; and

inferring the variable widths of the second variables from the variable widths of the first variables.

5. A method as recited in claim 1, wherein the libraries are written in Handel-C.

6. A method as recited in claim 1, wherein each macro corresponds to a unique graphics adapter.

7. A computer program product for using a library map during the design of cores, comprising:

(a) computer code for determining a plurality of macros which specify an interface; and

(b) computer code for utilizing one of a plurality of libraries during the execution of each of macro;

(c) wherein each macro is capable of being executed utilizing different libraries.

8. A computer program product as recited in claim 7, wherein the macros are executed on a co-processor which is capable of executing the macros utilizing different libraries.

9. A computer program product as recited in claim 7, wherein the macros are compiled in a file.
