Inventor: ZIEGLER ELDON W JR
IPC: H03H21/00
Filed: 1991-02-07
Abstract: A digital virtual earth active cancellation system which receives a phenomena input signal representing residual phenomena to be cancelled and has an adaptive filter which generates a cancellation signal. A system impulse response is convolved with the cancellation signal and is subtracted from the input signal to produce an estimate of noise. This substantially eliminates the problems associated with destructive feedback due to phase shifts. The residual signal is used to control an adaptive filter that receives the estimated noise as an input. The adaptive filter produces the cancellation signal by filtering the estimated noise with filter weights that are adapted using the residual signal and the estimated noise convolved with the system impulse response.

Abstract: Les impulsions d'horloge émises par un oscillateur maître (10) sont réparties dans un système d'ordinateur à processeurs multiples (17A-17N) de façon qu'elles arrivent à un grand nombre de points d'utilisation (21) situés dans des grappes d'exploitation (#1, #2 --- #N) de modules avec des tolérances de temps extrêmement étroites entre chacune de ces grappes. Les retards relatifs à chaque composant (31, 41), à chaque connexion électrique ou optique (25, 34, 47), à chaque câble (24, 34, 48) ou similaire sont déterminés par des mesures directes ou par l'utilisation de caractéristiques normalisées. Un budget de temps de retard pour chaque voie d'impulsions d'horloge complète depuis le point de divergence initiale (31) à partir de la source de l'horloge mère (20) jusqu'au point de sortie de la puce finale (21, 162) est enregistré et totalisé. Des composants (56, 58) pouvant introduire des quantités prédéterminées de temps de retard sont incorporés dans certaines voies ou dans toutes les voies d'impulsions d'horloge. Ces composants sont adaptés de façon à compenser les différences déterminées par les budgets de voies d'impulsions d'horloge. Les voies d'impulsions d'horloge sont mises en oeuvre dans des composants électriques soit individuellement, soit en combinaison avec des composants optiques (150), soit dans pratiquement toutes les configurations optiques. Afin de réguler le désalignement optique, un ensemble (145) d'éléments optiques (174, 176, 177) peuvent être déplacés physiquement dans un sens coaxial les uns par rapport aux autres. Les réseaux de correction de désalignement emploient une combinaison unique de configurations sélectionnables de lignes de retard à action approximative (56) et précise (58), qui sont mises en oeuvre par des composants électriques, des composants optiques ou par une combinaison de ces deux types de composants.
