CA 2189148

A computing device, which may be implemented as an integrated circuit, is constructed of a microprocessor (30) and one or more neural network co-processors (32). The microprocessor (30) normally executes programs which transfer data to the neural network co- processors (32), which are used to compute complicated mathematical functions. Direct Memory Access (DMA) is also used to transfer data. Each neural network co-processor (32) interfaces to the microprocessor in a manner substantially similar to that of a conventional memory device. The co-processor (32) does not require any instructions and is configured to execute mathematical operations simply by being pre-loaded with gating functions and weight values. In addition, the co-processor (32) executes a plurality of arithmetic operations in parallel, and the results of such operations are simply read from the co-processor.

Un dispositif informatique, pouvant se présenter sous forme d'un circuit intégré, est constitué d'un microprocesseur (30) et d'au moins un coprocesseur (32) à réseau neuronal. Le microprocesseur (30) exécute normalement des programmes qui transfèrent des données aux coprocesseurs (32) à réseau neuronal, utilisées pour calculer des fonctions mathématiques compliquées. Un accès direct à la mémoire est également utilisé pour transférer des données. Chaque coprocesseur (32) à réseau neuronal est relié au microprocesseur d'une manière sensiblement similaire à celle d'un dispositif mémoire classique. Le coprocesseur (32) ne nécessité aucune instruction et sa configuration lui permet d'exécuter des opérations mathématiques alors qu'il est préchargé avec des fonctions de déclenchement et des valeurs de pondération. En outre, le coprocesseur (32) exécute en parallèle plusieurs opérations arithmétiques et les résultats de ces opérations sont simplement lus dans le coprocesseur.
