Filed:

Jun 26, 2000

Appl. No.:

09/602713

Inventors:

Richard A. Ross - Berkeley CA, US

Assignee:

Hewlett-Packard and Development Company, L.P. - Houston TX

International Classification:

G06F 17/30

US Classification:

707101, 707 10, 717153

Abstract:

Methods for processing condensed computer code are disclosed herein. The condensed computer code includes index references that take the place of code structures found in corresponding executable computer code. The condensed computer code, as well as one or more lists that map the index references found in the condensed computer code to the code structures found in the executable computer code, are transmitted to a user system. The condensed computer code is executed by fetching opcodes and operands from the computer code, and then executing the fetched opcodes. If a fetched operand is an index reference, the fetched operand is resolved by using the index reference as an index into one of the lists.

Filed:

Jun 13, 2005

Appl. No.:

11/151801

Inventors:

Richard A. Ross - Berkeley CA, US

International Classification:

G06F 12/00

US Classification:

711213, 711137, 712207

Abstract:

Cache prefetching algorithm uses previously requested address and data patterns to predict future data needs and prefetch such data from memory into cache. A requested address is compared to previously requested addresses and returned data to compute a set of increments, and the set of increments is added to the currently requested address and returned data to generate a set of prefetch candidates. Weight functions are used to prioritize prefetch candidates. The prefetching method requires no changes to application code or operation system (OS) and is transparent to the compiler and the processor. The prefetching method comprises a parallel algorithm well-suited to implementation on an application-specific integrated circuit (ASIC) or field-programmable gate array (FPGA), or to integration into a processor.

Appl. No.:

11/758204

Inventors:

Richard A. Ross - Berkeley CA, US

International Classification:

G06F 9/45
G06F 3/00

US Classification:

717140, 715751, 715758

Abstract:

Systems and methods for processing message subscriptions using pre-compiled code-blocks for expression evaluation. In one embodiment, a system is configured find a set of unique clauses in a set of expressions representing message subscriptions, express the expressions as Boolean functions of the unique clauses, and compile the Boolean functions into a set of assembly instructions for efficient expression evaluation. In another embodiment, a system is configured to receive a message, generate a set of True/False assignments to a set of clauses in a set of expressions, and evaluate the expressions using an efficient compiled expression evaluation code-block.

US Patent:

Filed:

May 16, 2007

Appl. No.:

11/749675

Inventors:

Richard A. Ross - Berkeley CA, US

International Classification:

G06F 9/45
G06F 9/44

US Classification:

717143, 717116, 717136, 717142

Abstract:

Client Native method Interface (CNI) minimizing eXtensible Mark-up Language (XML) parsing is provided using array pair data structures. An empty array pair is passed to an engine from client code via a CNI call. The engine parses the XML document and fills the array pair with fixed width elements. The filled array pair is passed back to client code. The client code iterates through the elements in the array pair and invokes the appropriate handlers or builds appropriate tree objects for Document Object Model parsing. Thus, one CNI call passes the empty array pair from client code to the engine, and the filled array pair is returned from the engine to client code. Individual sets of CNI calls for each element are avoided, minimizing the number of CNI calls. Further, since elements in the array pair are of fixed width, they can be processed more efficiently by the client code.

Inventors:

Richard J. Ross - Moraga CA

Assignee:

RJR Polymers, Inc. - Oakland CA

International Classification:

B41F 140

US Classification:

101324

Abstract:

Printing of a pattern from a die to a surface is performed by immersing the die in a bath of liquid print material with the die surface facing upward, then either lowering the bath liquid level or raising the die to expose the die surface wet with liquid print material, and contacting the surface to be printed with the wet die surface.

Assignee:

International Classification:

B29C 4500

US Classification:

156245

Abstract:

Electronic packages that consist of dies sealed within hollow plastic enclosures with electrically conductive leads penetrating the enclosure walls to access the die circuitry are manufactured by applying a heat-curable adhesive to the leads at only those locations where the surfaces of the leads will interface with the enclosure material, molding the package around the leads, and curing the adhesive during the molding process or during a post-cure. The adhesive is formulated to form a gas-tight seal around the leads and to maintain the seal during the thermal cycling that the components are exposed to during the typical procedures involved in manufacturing the packages and in making the electrical connections to other circuitry, as well as the typical environmental changes that the finished and installed product is exposed to during use. In particular, the adhesive is selected to accommodate differences in the coefficients of thermal expansion between the leads and the enclosure material while still maintaining a vapor-tight seal.
