摘要： This invention relates to the art of computer system emulation and, more particularly, to a computer system emulator in which the functions normally performed by the hardware in a legacy central processor unit are emulated by a software program. The invention is to enhance the emulated instruction set beyond that of the legacy machine such to include as new single instructions a method for invoking operating system functions, with the machine coding of the operating system functions now being performed by machine code native to the new host machine, rather than as a sequence of emulated legacy instructions.

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 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 is disclosed for determining with computing apparatus an adequate number of clusters for summarizing result data that includes a large number of observation data points. The summary data includes a small number of samples of data from each cluster with the number of clusters being large enough to provide a good summary of all the result data without being so large as to make it difficult for one skilled in the art to examine visually all of the summary data generated by the computing apparatus.

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.
