Abstract

System and method for deploying and executing a program, e.g., a graphical program, on an embedded device. The program and a plurality of execution system components are stored on a host computer. The program is analyzed programmatically to determine a subset of the plurality of components required for execution of the program. The subset of components and the program are combined into a file while preserving execution order of the program. The file is transmitted to the device. The file is used to construct a combined program which includes executable code for the program and the subset of components. The device includes a minimal execution engine which executes the subset of components to execute the program. The file may be streamed to the device for streaming execution, where received portions of the subset of components needed for execution of received portions of the program are stored until no longer needed.

wherein the plurality of components are determined based on functionality present in the program.

7. The method of claim 1,

wherein the file comprises a flat file, wherein the file is created by combining the plurality of components and the program into the file.

8. The method of claim 7,

wherein said combining comprises interspersing the plurality of components with the program according to an execution order of the program;

and

wherein the first and the second parts of the file are arranged according to the execution order of the program.

9. The method of claim 1, wherein the program execution system comprises one or more of:

a minimal execution engine;

or

a network manager.

10. The method of claim 1,

wherein said executing the first portion and the second portion of the combined program comprises executing each of the first and the second portions of the combined program after said storing each respective portion of the combined program.

11. A computer-implemented method for creating and executing a program, the method comprising:

generating a file based on a program and one or more execution modules, wherein the program is operable to execute on an embedded device, wherein the one or more execution modules are usable to execute the program, wherein the one or more execution modules comprise a minimal execution system;

transmitting the file to the embedded device, wherein the file is transmitted in two or more parts;

the embedded device receiving a first of the two or more parts of the file;

the embedded device constructing a combined program based on the first of the two or more parts of the file, wherein the combined program includes program code from the program and execution module code for executing the program code;

the embedded device receiving a second of the two or more parts of the file;

the embedded device constructing the combined program based on the second part of the file; and

the embedded device executing the program using the minimal program execution system.

12. The method of claim 11, further comprising:

the embedded device deleting the second of the two or more parts of the file.

13. The method of claim 11, further comprising:

programmatically analyzing the program to determine required execution modules for execution of the program; and
