Patent

CA 2093815

A method and apparatus for downloading instructions and other information to a peripheral controller (103) for use in an Industry Standard Architecture (ISA) compatible computer (102) provides a system which downloads instructions from the ISA compatible computer (102) to a random access memory (RAM) (109) accessible by the peripheral controller (103). The peripheral controller (103) then executes these instructions to emulate the functions of conventional INTEL 8042 and 8742 series integrated circuits. The peripheral controller (103) also provides other features not provided by the conventional 8042 or 8742 by executing other downloaded instructions located in the RAM.

Un procédé et un appareil servant à télécharger des instructions et d'autres informations vers un régisseur de périphérique (103) utilisé dans un ordinateur (102) compatible ISA (Industry Standard Architecture), utilisent un système permettant de télécharger des instructions à partir de l'ordinateur compatible ISA (102) vers une mémoire vive (109) accessible au régisseur de périphérique (103). Le régisseur de périphérique (103) exécute ensuite ces instructions afin d'émuler les fonctions de circuits intégrés des séries INTEL 8042 et 8742 classiques. Le régisseur de périphérique (103) présente aussi d'autres fonctions non comprises dans les 8042 ou 8742 classiques lorsqu'il exécute d'autres instructions téléchargées se trouvant dans la mémoire vive.
