  • Patent number: 9582278
    Abstract: A system for generating processor hardware supports a language for significant extensions to the processor instruction set, where the designer specifies only the semantics of the new instructions and the system generates other logic. The extension language provides for the addition of processor state, including register files, and instructions that operate on that state. The language also provides for new data types to be added to the compiler to represent the state added. It allows separate specification of reference semantics and instruction implementation, and uses this to automate design verification. In addition, the system generates formatted instruction set documentation from the language specification.

  • Publication number: 20090125866
    Abstract: A method for decomposing a target pattern containing features to be printed on a wafer into multiple patterns. The method includes the steps of segmenting the target pattern into a plurality of patches; identifying critical features within each patch which violate minimum spacing requirements; generating a critical group graph for each of the plurality of patches having critical features, where the critical group graph of a given patch defines a coloring scheme of the critical features within the given patch, and the critical group graph identifies critical features extending into adjacent patches to the given patch; generating a global critical group graph for the target pattern, where the global critical group graph includes the critical group graphs of each of the plurality of patches, and an identification of the features extending into adjacent patches; and coloring the target pattern based on the coloring scheme defined by the global critical group graph.

  • Publication number: 20080220056
    Abstract: The present invention is based on the finding that the artificial induction of hepatic stellate cell (HSC) apoptosis in vivo can promote the resolution of liver fibrosis. Thus, the present invention provides methods for treating liver disease in a subject involving administration of an inducer of apoptosis which is capable of selectively inducing hepatic stellate cell apoptosis in the liver of the subject or of an agent which is capable of giving rise to such an inducer in the subject. In addition, the invention provides methods for treating liver fibrosis in a subject comprising the selective delivery of an inducer of apoptosis specifically to the hepatic stellate cells of the subject or of an agent which is capable of giving rise to an inducer of hepatic stellate cell apoptosis.

  • Patent number: 6477697
    Abstract: An automated processor design tool uses a description of customized processor instruction set extensions in a standardized language to develop a configurable definition of a target instruction set, a Hardware Description Language description of circuitry necessary to implement the instruction set, and development tools such as a compiler, assembler, debugger and simulator which can be used to develop applications for the processor and to verify it. The standardized language is capable of handling instruction set extensions which modify processor state or use configurable processors. By providing a constrained domain of extensions and optimizations, the process can be automated to a high degree, thereby facilitating fast and reliable development.
