Patent number: 6651163Abstract: A mechanism for exception and interrupt handling in multithreaded multiprocessors is provided. The mechanism allows the handling of exceptions and interruptions in a multithreaded multiprocessor computer, while hiding the multiprocessor nature of the computer from the operating system. Generally, when an operating system is cognizant of the multiprocessor nature of a computer, additional overhead may be required when handling exceptions and interruptions. Due to the overhead involved in saving and restoring processing states, the performance of a processor may be significantly impacted. Additional circuitry is provided which allows the multiprocessor nature of the computer to be hidden from the operating system, while minimizing the overhead necessary for proper handling.Type: GrantFiled: March 8, 2000Date of Patent: November 18, 2003Assignee: Advanced Micro Devices, Inc.Inventors: Uwe Kranich, David S. Christie

Patent number: 6651128Abstract: Several different systems and methods are described involving arbitration between asynchronous and isochronous data for access to a data transport resource (e.g., a bus or a memory controller). A first embodiment of a system (e.g., a computer system or a communication system) includes an arbiter coupled to the data transport resource, an asynchronous queue for storing asynchronous data, and an isochronous queue for storing isochronous data. The isochronous queue has a data level range divided into multiple portions. A number of memory locations within the isochronous queue may define the data level range of the isochronous queue. The arbiter arbitrates between the asynchronous queue and the isochronous queue for access to the data transport resource dependent upon the portion of the data level range in which a level of data resides within the isochronous queue. The level of data within the isochronous queue may be a number of memory locations between a write pointer and a read pointer.Type: GrantFiled: February 10, 2000Date of Patent: November 18, 2003Assignee: Advanced Micro Devices, Inc.Inventor: Dale E.

Patent number: 6650422Abstract: The present invention is directed to a method and a system for non-destructively, efficiently and accurately detecting asymmetry in the profile of a feature formed on a wafer during the process of semiconductor fabrication. The method encompasses directing a beam of light or radiation at a feature and detecting a reflected beam associated therewith. Data associated with the reflected beam is correlated with data associated with known feature profiles to ascertain profile characteristics associated with the feature of interest.

Patent number: 6651161Abstract: A processor employs a store to load forward (STLF) predictor which may indicate, for dispatching loads, a dependency on a store. The dependency is indicated for a store which, during a previous execution, interfered with the execution of the load. Since a dependency is indicated on the store, the load is prevented from scheduling and/or executing prior to the store. The STLF predictor is trained with information for a particular load and store in response to executing the load and store and detecting the interference. Additionally, the STLF predictor may be untrained (e.g. information for a particular load and store may be deleted) if a load is indicated by the STLF predictor as dependent upon a particular store and the dependency does not actually occur. In one implementation, the STLF predictor records at least a portion of the PC of a store which interferes with the load in a first table indexed by the load PC.Type: GrantFiled: January 3, 2000Date of Patent: November 18, 2003Assignee: Advanced Micro Devices, Inc.Inventors: James B. Keller, Thomas S. Green, Wei-Han Lien, Ramsey W. Haddad

Patent number: 6651172Abstract: A novel method is provided for initializing a data processing system having registers programmable with configuration data read from a non-volatile memory at power-up. The method includes segmenting the non-volatile memory into a first portion for storing first data, and a second portion for storing second data having lower priority than the first data.

Patent number: 6649426Abstract: The present invention relates to systems and methods to regulate spacer deposition. The present invention employs a spacer deposition controller to control a spacer deposition component that deposits a spacer on a portion of a wafer. During and/or after spacer deposition, light can be directed at the spacer, wherein light reflected from the spacer is measured to determine parameters associated with the spacer deposition process. A processor operatively coupled to a measurement system and the spacer deposition controller utilizes the parameters to determine if the spacer process is proceeding in a suitable manner via comparing the measured parameters with stored acceptable parameters. If it is determined that the spacer deposition process is not proceeding as desired, then the measured parameters can be employed by the spacer deposition controller to adjust the spacer deposition process on the portion of the wafer and on subsequent portions of wafers.Type: GrantFiled: June 28, 2001Date of Patent: November 18, 2003Assignee: Advanced Micro Devices, Inc.Inventors: Bharath Rangarajan, Michael K.

Patent number: 6645868Abstract: Shallow trench isolation among transistors and other devices on a semiconductor substrate is provided by initially forming a layer of highly absorbing silicon rich nitride to serve as a hardmask between a semiconductor substrate and a photoresist. The highly absorbing layer of silicon rich nitride has an extinction coefficient (k)>0.5. As reflected light passes through the layer of silicon rich nitride, a substantially amount of light is absorbed therein thereby blocking such reflected light from negatively interfering with patterning of the photoresist during photo-lithography. Following patterning of the photoresist, isolation trenches are formed in the semiconductor substrate by etching through the silicon rich nitride in accordance with the pattern formed on the photoresist.Type: GrantFiled: May 17, 2001Date of Patent: November 11, 2003Assignee: Advanced Micro Devices, Inc.Inventors: Carl P.
