Patent CA-2081475-C (CA)
Title: Multilanguage optimizing compiler using templates in multiple pass code generation
Inventor: FAIMAN ROBERT NEIL JR
IPC: G06F9/45
Filed: 1992-02-18
Granted: 1998-05-05
Abstract: A compiler framework uses a generic "shell" or control and sequencing mechanism, and a generic back end (where the code generator is target-specific). The generic back end includes the functions of optimization, register and memory allocation, and code generation. The shell may be executed on various host computers, and the code generation function of the back end may be targeted for any of a number of computer architectures. A front end is tailored for each different source language, such as Cobol, Fortran, Pascal, C, C+ +, Ada, etc. The front end scans and parses the source code modules, and generates from them an intermediate language ("IL") representation of the programs expressed in the source code. This IL is constructed to represent any of the source code languages in a universal manner, so the interface between the front end and back end is of a standard format, and need not be rewritten for each language-specific front end. The IL representation generated by the front end is based upon a tuple as the elemental unit, where each tuple represents a single operation to be performed, such as a load, a store, an add, a label, a branch, etc. A data structure is created by the front end for each tuple, with fields for various necessary information.  One feature of the invention is a mechanism for representing effects and dependencies in the interface between front end and back end; a tuple has an effect if it writes to memory, and has a dependency if it reads from a location which some other node may write to. A mechanism of source language is provided for describing the effects of program execution.  Another feature is the use in the optimization part of the compiler of a method for analyzing induction variables, where the improvement is to use the side effects sets used to construct IDEF sets. Another feature is a mechanism for "folding constants" (referred to as K-folding or a KFOLD routine), included as one of the optimizations.  A further feature is the type definition mechanism, referred to as the TD module, which provides mechanisms used by the front end and the compiler of the back end in constructing program type information to be incorporated in an object module for use by a linker or debugger. Another feature is a method for doing code generation using code templates in a multipass manner.

Abstract: A method for determining the extent of sepsis in a patient by detecting the presence of antigen indicative of sepsis in a patient blood-derived test sample containing white blood cell fractions, the method comprises: i) incubating the test sample with antibodies specific to the antigens indicative of sepsis to form antibody/antigen complexes, ii) introducing a chemiluminescent compound to the test sample, and iii) allowing the antibody/antigen complexes to interact with the white blood cell fractions to produce oxidants.      After the above steps are conducted in any order then: iv) the oxidants reacting with the chemiluminescent compounds cause luminescent light to be emitted from the test sample, and v) the emitted light over a predetermined period is measured and correlated with the extent of sepsis.

Abstract: The present invention provides a disk player, which is capable of changing the playing linear velocity by a multiple stages to shorten the reading time.  The disk player includes the conventional motor, and an optical pick-up.  A first clock section generates master clock signals,  for changing the frequency of the master clock signals by multiple stages, as well as an oscillating circuit for generating standard clock signals.    First  and  second divider  circuits  divide  the standard clock signals and generate first and second divided signals.  A phase comparing circuit compares the phases of the first and second divided signals and generates phase-deviation signals which correspond to the phase deviation thereof.  A processing   section  generates   setting   signals,   which respectively define the dividing ratio of the first and second divider circuits.   A second clock section generates second clock signals whose frequency is equal to the frequency of synchronizing signals.  A comparing section compares mutual frequency and phase of the master clock signals and the second signals and generates deviation signals whose voltage level corresponds to the differences of the frequency and the phase thereof.  A drive section sends drive signals, whose voltage level changes according to voltage changes of the deviation signals, to the motor.  Thus, the drive section controls the motor so as to synchronize the frequency and the phase of the second clock signals with those of the master clock signals.
