Appl. No.:

13/752296

Inventors:

Joel J. Koshy - Davis CA, US

Assignee:

The Regents of the University of California - Oakland CA

International Classification:

G06F 15/177
G06F 15/173
G06F 9/445
G06F 13/00
G11C 11/34

US Classification:

709220, 709221, 709222, 709224, 709226, 717172, 711103, 36518533

Abstract:

Systems and techniques for incrementally updating a software stack are described. The software stack can be stored on a flash memory device on a target device. A server computer can receive a modification to a function that is part of the software stack, wherein additional memory is allocated on the flash memory device to allow the function increase in size via a software update. Next, a new memory layout can be determined for storing functions in the software stack based on the modification to the function. The server computer can then determine changes to a set of memory pages on the flash memory device based on the new memory layout. Next, the server computer can send the changes to the set of memory pages to the target device.

Abstract:

One embodiment of the present invention provides a method and a system for synthesizing a scalable and incrementally updatable system software infrastructure for sensor networks. During operation, the system receives a specification for an application and a specification for target devices. The system analyzes these specifications in order to identify a set of software components required to support the application, and then proceeds to synthesize a customizable software stack that accommodates the identified set of software components on a specified target device. This process generates a minimal, resource-efficient software stack for a specific application on the specified target device.
