Patent number: 6925637Abstract: A method and system of carrying out garbage collection in a computer system. Specifically, the method and system utilize low contention grey object sets for concurrent marking garbage collection. A garbage collector traces memory objects and identifies memory objects according to a three-color abstraction, identifying a memory object with a certain color if that memory object itself has been encountered by the garbage collector, but some of the objects to which the memory object refers have not yet been encountered. A packet manager organizes memory objects identified with the certain color into packets, provides services to obtain empty or partially full packets, and obtain full or partially full packets, and verifies whether a packet of the certain color is being accessed by one of the threads of the garbage collector.Type: GrantFiled: May 16, 2001Date of Patent: August 2, 2005Assignee: Esmertec AGInventors: Stephen Paul Thomas, William Thomas Charnell, Stephen Darnell, Blaise Abel Alec Dias, Philippa Joy Guthrie, Jeremy Paul Kramskoy, Jeremy James Sexton, Michael John Wynn, Keith Rautenback, Wayne Plummer

Patent number: 6901587Abstract: A method and a system of cache management using spatial separation of outliers. The system includes a dynamic compiler arranged to create compiled fragments of code having dominant code blocks and outliers. Memory coupled to the dynamic compiler is managed by a compiler manager such that dominant code blocks are stored in one portion of the memory and the outliers are stored in another portion of the memory. Storing the dominant path code separate from the outliers increases efficiency of the system.Type: GrantFiled: May 16, 2001Date of Patent: May 31, 2005Assignee: Esmertec AGInventors: Jeremy Paul Kramskoy, William Thomas Charnell, Stephen Darnell, Blaise Abel Alec Dias, Philippa Joy Guthrie, Wayne Plummer, Jeremy James Sexton, Michael John Wynn, Keith Rautenbach, Stephen Paul Thomas

Patent number: 6799727Abstract: Flame-effect heating apparatus comprises a housing with walls defining an air duct extending therethrough. Simulated fuel is supported by the housing, externally of the duct, and at least one flame-effect generator is disposed in the duct. A light source is provided in the housing to illuminate both the simulated fuel and the flame-effect generator. A mirror is supported by the housing so that light reflected by the flame-effect generator is incident thereon. A wall of the housing which defines the air duct, is formed as a viewing screen on which light reflected by the mirror falls, the viewing screen being positioned higher than the simulated fuel. An electric fan causes air to flow through the air duct, so causing operation of the flame-effect generator, and a heat exchanger disposed in the duct warms air passing thereover.Type: GrantFiled: November 2, 2001Date of Patent: October 5, 2004Assignee: Smith's Environmental Products LimitedInventors: Gary Stanton Webster, Jeremy James Stanley

Patent number: 6691303Abstract: A method and system of testing and verifying computer code in a multi-threaded environment. The method includes testing a first piece of computer code that is an implementation of a specification against a second piece of computer code that is a different implementation of the specification. Corresponding synchronization points in the first and second pieces of code are defined and the first piece of code is executed to the first synchronization point of the first piece of code. A state message is generated and sent to the second piece of code. The second piece of code is executed to the first synchronization point of the second piece of code and then a state after message is generated and compared to the state before message. The synchronization points are generally selected from a group including conditional transfers of control, Method calls, Method returns, and backward transfers of control.Type: GrantFiled: May 16, 2001Date of Patent: February 10, 2004Assignee: Esmertec AGInventors: Philippa Joy Guthrie, William Thomas Charnell, Stephen Darnell, Blaise Abel Alec Dias, Wayne Plummer, Jeremy Paul Kramskoy, Jeremy James Sexton, Michael John Wynn, Keith Rautenback, Stephen Paul Thomas

Publication number: 20020165848Abstract: A method and structure for reducing search times. The method includes examining the entries in a list in turn beginning with the entry pointed to by a start pointer and continuing until the particular entry is found. The start pointer is then reset to point at the particular entry that was found. The next search will therefore begin to search at the location where the last search ended. Such a strategy increases the likelihood of locating the particular entry faster. The list of entries includes next entry pointers that point to another entry in the list such that the next entry pointers together form a closed loop. If the entire list is searched and the particular entry is not found, the search is aborted.Type: ApplicationFiled: May 16, 2001Publication date: November 7, 2002Applicant: Insignia Solutions, PLCInventors: Keith Rautenbach, William Thomas Charnell, Stephen Darnell, Blaise Abel Alec Dias, Philippa Joy Guthrie, Jeremy Paul Kramskoy, Jeremy James Sexton, Michael John Wynn, Wayne Plummer, Stephen Paul Thomas

Publication number: 20020112227Abstract: A dynamic compiler and method of compiling code to generate a dominate path and handle exceptions. The dynamic compiler includes an execution history recorder that is configured to record the number of times a fragment of code is interpreted. When the code is interpreted a threshold number of times, the code is queued for compilation. The execution history recorder also keeps track of where transfer of control came from and where transfer of control goes to for each fragment of code that is executed, thereby allowing for compilation of a dominant path of code. If the execution of code deviates from the dominant path of compiled code (such as when an exception occurs), a fallback interpreter is utilized to interpret the fragment of code to be executed.Type: ApplicationFiled: May 16, 2001Publication date: August 15, 2002Applicant: Insignia Solutions, PLC.Inventors: Jeremy Paul Kramskoy, William Thomas Charnell, Stephen Darnell, Blaise Abel Alec Dias, Philippa Joy Guthrie, Wayne Plummer, Jeremy James Sexton, Michael John Wynn, Keith Rautenbach, Stephen Paul Thomas
