摘要： As manufacturers of very fast and powerful commodity processors continue to improve the capabilities of their products, it has become practical to emulate the proprietary hardware and operating systems of powerful older computers on platforms built using commodity processors such that the manufacturers of the older computers can provide new systems which allow their customers to continue to use their highly-regarded proprietary legacy software on state-of-the-art new computer systems by emulating the older computer in software that runs on the new systems. In an example of the subject invention, a 64-bit Cobol Virtual Machine instruction provides the capability of adding to or improving the performance of legacy 36-bit Cobol code. Legacy Cobol instructions can be selectively diverted, in the host CPU, to a 64 bit Virtual Machine Implementation. The output legacy and new Cobol code is compiled in a dedicated implementation of the Cobol compiler, and the output of the special purpose compiler is emulated in a special purpose software emulator, separate from the main software emulator that handles the normal 36-bit stream of legacy code.

摘要： As fast and powerful commodity processors have been developed, it has become practical to emulate on platforms built using commodity processors the proprietary hardware systems of powerful older computers. High performance is typically a key requirement for a system even when built using emulation software. In a hardware design many special cases and conditions which may cause exceptions are detected by logic operating in parallel with the instruction execution. In software these checks can cost extra cycles of processor time during emulation of each instruction and be a significant detriment to performance. Avoiding some of these checks by relying upon the underlying hardware checks of the host system and then using a signal handler and special software to recover from these signals is a way to improve the performance and simplify the coding of the software emulation system.

摘要： A method is disclosed for translating by a computer system of a COBOL computer program into a translated computer program in a readable and maintainable syntax in an object oriented programming language. The translated program including variable names equivalent to the original COBOL variable names and with attributes described in COBOL syntax. The translating method further providing for memory allocation in the translated computer program for storage of “COBOL” variables compatible with that of the original COBOL program; a description of program flow that is readable, and utilizing arithmetic operators to describe operations between COBOL variables. Also disclosed is a special object oriented run-time library for creating and performing operations between COBOL numeric objects, including maintaining storage of variable content in the original COBOL format, and for enabling readability of the translated source code by allowing arguments for variable type descriptions to be expressed in COBOL syntax.

摘要： In order to gather, store temporarily and deliver (if needed) central processor safestore information, a multiphase clock is employed to capture (one full clock cycle behind) the safestore information which typically includes all software visible registers in all (or selected) data manipulation chips of the CPU by routing the safestore information through temporary storage (under the influence of the multiphase clock) in a cache data array and into a special purpose XRAM module. Thus, upon the sensing of a fault, valid safestore information is available in the XRAM for analysis and, if appropriate, resumption of operation at a sequential point just previous to that at which the fault occurred.

摘要： A method and apparatus is disclosed for compilation of an original Cobol program with support for improved performance by increased parallelism during execution using multiple threads of processing. The approach includes a two stage compilation process, the first compilation/translation step by a first specialized compiler/translator that takes as input a Cobol source program that includes parallelization directives, and produces as output an intermediate computer program in a second computer programming language, the intermediate program including parallelization directives in the second computer programming language. The intermediate program is then compiled utilizing a selected second compiler that provides support for parallelism described in the second programming language. The approach optionally allows for use of pragmas serving as parallelization directives to the compiler in the original Cobol program or in the intermediate program.

摘要： A method and apparatus is disclosed providing an improvement in performance for arithmetic computations by a computer system for calculations which include decimal numeric variables. The improvement in at least one embodiment includes use of a special compiler in cooperation with a special decimal numeric subroutine library. The compiler provides comparative alignment information based upon comparing alignments of a plurality of decimal variables. The decimal subroutine library can then provide improved performance at run time by utilizing the information compared by the compiler at compiler time rather than making those computations repeatedly at run time.

摘要： A method and apparatus is disclosed for compilation of an original Cobol program and building an executable program with support for improved performance by increased parallelism during execution using multiple threads of processing. The approach includes a compilation (or translation) step utilizing a first compiler or translating program which is a parallel aware translating first compiler. The parallel aware first compiler is a specialized compiler/translator which takes as input a Cobol source program, and produces as output an intermediate computer program in a second computer programming language, the intermediate program including parallelization directives, the intermediate program intended for further compilation utilizing an existing selected second compiler, the second compiler providing support for parallelism for programs described in the second programming language. The approach optionally allows for use of pragmas serving as parallelization directives to the compiler in the original Cobol program or in the intermediate program.
