Filed:

Nov 17, 2003

Appl. No.:

10/716392

Inventors:

Barry James Curtis - Amesbury MA, US
Robert W. Beckwith - Barnstable MA, US
Richard Neisius - Centerville MA, US

International Classification:

B32B 29/00

US Classification:

428338, 428339, 428532, 428534, 428536, 4285377, 524 13, 524 16, 524567, 524569

Abstract:

Composite coated wood products, and methods to produce such products, are described by embodiments of the invention. Composite layers may comprise polymer and fillers, such as organic fillers and inorganic fillers. The composite layers may also be foamed in some embodiments of the invention. Such composite coated wood products may be structural or non-structural pieces that may provide safe, economical, easy to manufacture construction products that may be utilized with wood composites, and other plastic composites. Such products may also promote uniformity of appearance in objects constructed with the composite coated wood products in a variety of applications.

Abstract:

A data processing system, wherein the central processing unit has an arithmetic element for processing data in response to machine program instructions and a control store for microcode program storage responsive to the machine instructions for implementing the instruction, has an improved arithmetic unit for enabling higher throughput without substantially increasing hardware cost. The arithmetic unit has a reconfigurable arithmetic logic unit which is controlled in response to both hardware generated data signals and microcode generated data signals. A data string manipulation circuitry provides for aligning data strings for processing by the arithmetic logic unit. Circuitry is provided, responsive to a decoded machine instruction, for generating control signals for configuring the arithmetic unit and for controlling the data string manipulation circuitry. As a result, the number of microcode steps needed to implement particular decimal and string manipulation machine instructions is significantly reduced, thereby saving machine cycles, while the additional hardware cost is very modest.
