| Abstract: | A system and method are described for performing data processing using shared memory. In one embodiment, a first application programming engine is employed to process first application programming-based requests. Additionally, a second application programming engine is employed to process second application programming-based requests. The first and second application programming engines are integrated using a memory to provide a common access to both the first and second programming engines. |
