Title (EN) INTERRUPTIBLE TRIGONOMETRIC OPERATIONS
(FR) OPÉRATIONS TRIGONOMÉTRIQUES INTERRUPTIBLES
Abstract:
(EN) Trigonometric functions are computed by executing (1702) an interruptible iterative CORDIC operation to an intermediate result, with individual or multiple iterations of the CORDIC operation performed using specialized hardware for computing CORDIC operations. Upon receipt of an interrupt (1704), the CORDIC operation is paused (1706), and one or more other processor tasks are executed (1708) with a processor.
(FR) La présente invention concerne des fonctions trigonométriques calculées par exécution (1702) d'une opération CORDIC itérative interruptible à un résultat intermédiaire, des itérations individuelles ou multiples de l'opération CORDIC étant effectuées à l'aide d'un matériel spécialisé pour calculer des opérations CORDIC. Lors de la réception d'une interruption (1704), l'opération CORDIC est mise en pause (1706) et une ou plusieurs autres tâches de processeur sont exécutées (1708) par un processeur.
