Abstract
The present invention relates to an information processing apparatus, an information processing method and a program for simplifying an interrupt process to reduce time needed for the interrupt process. If it is determined in step Sthat a network card pointer and a CPU clear pointer fail to match each other, i.e., that there is a packet area corresponding to a packet used in an executed DMA transfer process and having not undergone a DMA transfer complete process, processing proceeds to step S. An interrupt generator sets a completion status as an interrupt status and proceeds to step S. In step S, the interrupt generator generates an interrupt signal. If it is determined in step Sthat there is not a packet area corresponding to a packet used in an executed DMA transfer process and having not undergone a DMA transfer complete process, processing proceeds to step S. The interrupt generator clears the completion status. The present invention is applicable to a network card, for example.
