NumberTitleIssue Date
5394347Method and apparatus for generating tests for structures expressed as extended finite state machines
A method for generating test programs for an implementation of a specification that has been modeled as an extended finite state machine (EFSM), the EFSM including vertices and transitions, where the transitions represent functions to be performed by the ...

5371889Journalling optimization system and method for distributed computations
A protocol analysis system is provided with data specifying the defined states of processes participating in a distributed computation. State transitions between states are specified as being enabled by (A) receiving a message, (B) unreliably sending a me...

5367683Smart recompilation of performing matchup/difference after code generation
A method and system for compiling a source program using smart recompilation. The invention allows fragments to contain "invocation specific" information, which is generated during a code generation phase of compilation. A hint generator attempts to prese...

5367573Signature data object
A "signature data object" (SDO) is a machine-readable structured data record which a signer may associate with a parent object, e.g., an electronic document. An SDO comprises three required encoded parts: A signature header structure; a signature data str...

5341478Methods and apparatus for providing dynamic invocation of applications in a distributed heterogeneous environment
A method and apparatus providing for the interaction of processes in an object-oriented manner by which a system manages "classes" of data instances and applications rather than managing the data itself. The names of classes may be stored in a data base w...

5325528Distributed computation recovery management system and method
A protocol analysis system is provided with data specifying the defined states of processes participating in a distributed computation. State transitions between states are specified as being enabled by (A) receiving a message, (B) unreliably sending a me...

5307504System and method for preserving instruction granularity when translating program code from a computer having a first architecture to a computer having a second reduced architecture during the occurrence of interrupts due to asynchronous events
A computer program of complex instruction set code (CISC) is translated to produce a program of reduced instruction set code (RISC). Each CISC instruction is translated into a sequence of RISC instructions. The sequence includes in order four groups of in...

5297291System for linking program units by binding symbol vector index in the symbol table into calling image to obtain current value of the target image
An improved method for linking images at program activation is provided by use of a symbol vector in a sharable code image. The symbol vector is automatically constructed which the linker and operating system use to effect fast lookup of symbol values at ...

5267175Data base access mechanism for rules utilized by a synthesis procedure for logic circuit design
In a circuit design synthesis procedure in which the pointers are added to the data base to permit a path through the circuit to be followed, a qualified object is defined to be a data object that permits access expressed by a sequence (or chain) of acces...
