Abstract:

The present invention is a systematic and data-driven-decomposition (DDD) method and apparatus for use in VLSI synthesis. The invention decomposes a high level program circuit description into a collection of small and highly concurrent modules that can be implemented directly into transistor networks. This enables an automatic implementation of a decomposition process currently done by hand. Unlike prior art syntax-based decompositions, the method of the present invention examines data dependencies in the process' computation, and then attempts to eliminate unnecessary synchronization in the system. In one embodiment, the method comprises: a conversion to convert the input program into an intermediate Dynamic Single Assignment (DSA) form, a projection process to decompose the intermediate DSA into smaller concurrent processes, and a clustering process that optimally groups small concurrent processes to make up the final decomposition. Another embodiment is a decomposition, projection, and clustering tool implemented in computer program codes.

Abstract:

Methods and systems for facilitating payments with a mobile device are described. The methods include detecting a location of a mobile device, receiving identifying information from a user through the mobile device when the mobile device is near at least one merchant, generating a payment code, transmitting the payment code to the mobile device, receiving the payment code and a payment request from a merchant, and processing the payment request.
