International Classification:

G06F013/14

US Classification:

710305, 710308, 710309

Abstract:

A DSP device is disclosed having multiple DMA controllers with global DMA access to all volatile memory resources in the DSP device. In a preferred embodiment, each of the DMA controllers is coupled to each of the memory buses and is configured to control each of the memory buses. A memory bus multiplexer may be coupled between the subsystem memory bus and each of the DMA controllers, and an arbiter may be used to set the memory bus multiplexer so as to allow any one of the DMA controllers to control the memory bus. The memory bus may also be controlled by the host port interface via the memory bus multiplexer. A round-robin arbitration technique is used to provide each of the controllers and the host port interface fair access to the memory bus. This approach may advantageously provide increased flexibility in the use of DMA controllers to transfer data from place to place, with only a minimal increase in complexity.

International Classification:

G06F001/04

US Classification:

713322, 713324, 713600

Abstract:

A digital signal processing chip having a multiple processor cores with corresponding processor subsystems, a shared component, and a clock tree, is disclosed herein. A clock tree distributes clock signals to the processor cores and the shared component. The clock tree can be configured to disable one or more of the processor cores and the shared component by blocking the corresponding clock signal. This may advantageously conserve power. However, the clock tree is configured to preserve the clock signal to the shared component as long as at least one of the processor cores has not disabled the shared component. That is, to block the clock signal to the shared component, each of the processor cores must disable the shared component. The shared component may, for example, be a shared program memory or an arbiter for an external input/output port. The clock tree may include a register and a series of clock gates.

Appl. No.:

11/280165

Inventors:

Duy T. Nguyen - Houston TX, US

Assignee:

Huntsman Petrochemical Corporation - The Woodlands TX

International Classification:

D21H 23/22

US Classification:

162158, 510527

Abstract:

A chemical softening composition includes a amide-substituted quaternary imidazolinium salt, a nonionic surfactant, and a polyhydroxy compound for use in treating cellulosic materials including papers, textiles and fabrics. The chemical softening composition can be applied to papermaking fibers during a papermaking process to provide a softened paper web and product possessed of sufficient tensile strength for its regular employment. A chemical softening composition according to the invention can also be applied to fabric to soften the fabric, provide easier handling of the fabric, and also reduce the tendency of the fabric to generate and store static electricity.

International Classification:

C11D 3/37

US Classification:

510475, 510421, 510434, 510477, 510499

Abstract:

Provided herein are compositions useful as detergents in cleaning a wide variety of substrates, including hard surfaces and laundry. The compositions contain a water-soluble polymer, which is a co-polymer between a polymerizable amide and a second, ethylenically-unsaturated monomer. The polymerizable amide itself is prepared from an amine-capped, alkoxylated alcohol by reaction with maleic acid anhydride. Compositions according to the invention show enhanced cleaning performance and beneficial anti-redeposition properties.
