Patent CA-2022939-C (CA)
Title: Aromatic polyanhydride compositions
Inventor: DOMB ABRAHAM J
IPC: A61K9/70
Filed: 1990-08-08
Granted: 2002-10-08
Abstract: Aromatic anhydride copolymers containing at least two aromatic diacid units, which are soluble in chloroform or dichloromethane to concentrations between approximately 0.5 to 50% weight/volume, melt at temperatures below 180°C, and have low crystallinity are disclosed. The copolymers may contain between 0 and approximately 30% aliphatic diacid units. All copolymers are insoluble in carbon tetrachloride, i.e., less than 0.1% polymer by weight/volume solvent). The desired properties are the result of adding between 10 and 90% of a second aromatic diacid, to the copolymer composition which introduces irregularity in the polymer chains that dramatically alter the polymer properties, decreasing the crystallinity and melting point and increasing the solubility in the common solvents, dichloromethane or chloroform. An additional decrease in Tg and MP, with an increase in flexibility, is obtained by adding small amount of aliphatic diacid, up to about 30%.

Abstract: Programme compilateur "framework" utilisant un système générique ou un mécanisme de régulation et de classement, et un processeur dorsal générique (pour lequel le générateur de code est spécifique au destinataire). Le processeur dorsal générique englobe les fonctions d'otpimisation, d'attribution de registre et de mémoire et de génération de code. Le système expert générique peut être réalisé sur divers ordinateurs centraux et la fonction génération de code du processeur dorsal peut être ciblée en fonction de l'une quelconque parmi plusieurs architectures d'ordinateur. Un processeur frontal est adapté à divers langages source, tels que le Cobolt, le Fortran, le Pascal, C, C++, Ada, etc. Le processeur frontal balaie et analyse les modules code source et élabore à partir de ceux-ci une représentation en langage intermédiaire ("IL") des programmes exprimés dans le code source. Cette représentation IL est conçue de manière à représenter l'un quelconque des langages code source de manière universelle de sorte que l'interface entre le processeur frontal et le processeur dorsal se présente sous une forme standard et n'est pas besoin d'être réécrite pour chaque processeur frontal ayant un langage spécifique. La représentation IL élaborée par le processeur frontal est basée sur un nuplet en tant qu'élément de base, dans lequel chaque nuplet représente une opération unique devant être exécutée - charge, mise en mémoire, addition, étiquettage, branchement, etc. Une structure de données est créée par le processeur frontal pour chaque nuplet, avec des champs pour diverses informations nécessaires. L'une des caractéristiques de l'invention réside dans son mécanisme de représentation des effets dépendances dans l'interface entre processeur frontal et processeur dorsal; un nuplet produisant un effet s'il écrit dans une mémoire et présentant une dépendance s'il lit d'un emplacement vers lequel un autre noeud peut écrire. Un mécanisme indépendant du langage source est prévu pour décrire les effets de l'exécution du programme. Une autre caractéristique réside dans l'utilisation, dans la partie optimisation du programme compilateur, d'une méthode d'analyse des variables d'induction, dans laquelle l'amélioration consiste à utiliser des ensembles d'effets secondaires utilisés pour élaborer des ensembles IDF. Une autre caractéristiques réside dans un mécanisme pour "repliages constants" (désigné par les termes "K-folding ou KFOLD routine"), constituant l'une des optimisations. Une autre caractéristique réside dans le mécanisme de définition de type, désigné "module TD", qui fournit des mécanismes utilisés par le processeur frontal et le programme compilateur du processeur dorsal dans les informations type de programme de construction devant être incorporées dans un module objet à l'usage d'un éditeur de lien ou d'un metteur au point. Une autre caractéristique est constituée par la méthode de génération de code d'instruction utilisant des gabarits de code selon un procédure multipasse.
