Albert Ren has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.

  • Patent number: 8924898
    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. Implementation of the processor circuitry can be optimized for various criteria such as area, power consumption, speed and the like. Once a processor configuration is developed, it can be tested and inputs to the system modified to iteratively optimize the processor implementation. By providing a constrained domain of extensions and optimizations, the process can be automated to a high degree, thereby facilitating fast and reliable development.

  • 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.
