merge to Unix signal discuss Talk Unix signal Merging individual signal pages date January 2012 Infobox Computing signal name SIGEMT non POSIX description Emulator trap action Abnormal termination of the process On some Unix like platforms, SIGEMT is the Signal computing signal sent to computer program s when an emulator trap occurs. The C preprocessor symbolic constant for SIGEMT is defined in code signal.h code . Symbolic signal names are used because signal numbers can vary across platforms. Etymology SIG is a common Prefix linguistics prefix for signal names. EMT is an abbreviation for emulator trap it is the name of an instruction on the highly influential PDP 11 architecture. Usage Expand section date January 2007 On the PDP 11 architecture, EMT, TRAP, BPT and IOT were instructions used for program traps. EMT was for system software, TRAP for programmer use, BPT for debugging , and IOT for input output I O routines. Currently EMT does not have a standardised usage. Solaris Operating System Solaris sends SIGEMT to new lightweight process es to enable them to reset hardware performance counters. ref cite web url http www.cs.duke.edu cgi bin man2.cgi?cpc bind cpu 3CPC 1 title cpc bind curlwp 3CPC accessdate 2007 01 24 date October 26, 2005 work Solaris man pages publisher Sun Microsystems, Inc.

LynxSecure is a Type 1 Embedded Hypervisor and separation kernel from LynuxWorks which utilizes system virtual machines to provide hardware virtualization for embedded systems built on multicore x86 architecture . LynxSecure supports paravirtualized Linux and LynxOS real time operating systems, as well as full virtualization of the Windows operating system. LynxSecure is built to conform to the Multiple Independent Levels of Security MILS Multiple Independent Levels of Security architecture so that virtualization can be used in embedded systems with requirements for high assurance. By default, LynxSecure uses an ARINC 653 based fixed cyclic scheduler to manage processing time, but dynamic scheduling policies are also permitted. operating system stub Category Free virtualization software ... more details

It is developed by Code Synthesis and dual license dual licensed under the GNU GPL and a proprietary license. Given an XML instance specification XML Schema W3C XML Schema , XSD e can produce three kinds of C mappings Embedded C Parser for event driven XML parsing, Embedded C Serializer for event driven XML serialization, and Embedded C Hybrid which provides a light weight, in memory object model on top of the other two mappings. The C Hybrid mapping generates C classes for types defined in XML Schema as well as parsing and serialization code. The C classes represent the data stored in XML as a statically typed, tree like object model and support fully in memory as well as partially in memory partially event driven XML processing. The C Parser mapping generates validating C parser skeletons for data types defined in XML Schema. One can then implement these parser skeletons to build a custom in memory representation or perform immediate processing as parts of the XML documents become available. Similarly, the Embedded C Serializer mapping generates validating C serializer skeletons for types defined in XML Schema which can be used to serialize application data to XML.

Multiple issues COI July 2010 advert January 2010 Objectivity DB is a commercial object database produced by Objectivity, Inc. It allows applications to make standard C , Java programming language Java , Python programming language Python or Smalltalk objects persistent without having to convert the data objects into the rows and columns used by a relational database management system RDBMS . Objectivity DB supports the most popular object oriented languages plus SQL ODBC and XML . It runs on Linux , LynxOS , UNIX and Microsoft Windows Windows platforms. All of the languages and platforms interoperate, with the Objectivity DB kernel taking care of compiler and hardware platform differences. History Objectivity, Inc. was founded in 1988 and brought Objectivity DB to the market in 1990. The corporate headquarters is in Sunnyvale, California Sunnyvale , California . The company was a founding member of both the Object Management Group OMG and the Object Data Management Group ODMG . The C , Java and Smalltalk interfaces for Objectivity DB incorporate the features defined in the ODMG 93 standard. Architectural features Objectivity DB is a distributed database that provides a single logical view across a federation of databases. It uses a distributed computing model that links a small software library with the client application. The client transparently communicates with remote servers that are functionally simpler than their equivalents in centralized database server architectures. There are lock, remote data transfer and query agent server processes. The distributed architecture helps make Objectivity DB inherently scalability scalable and reliability engineering reliable . It has sustained ingest rates in excess of one terabyte per hour while simultaneously supporting data fusion and query operations. ref http www.objectivity.com pages object oriented databases building high performance object oriented databases.html Building a High Throughput Data repository With Hig ... more details
