摘要： The invention relates to an arrangement and a method respectively for handling or getting access to a digital buffer in a digital buffer memory (JBUM) wherein to each digital buffer a set of pointers is arranged in a reference memory (REFM). The arrangement comprises a register arrangement (JBSR, JBER) defining the position of a digital buffer in the digital buffer memory (JBUM), an offset value, an address calculation arrangement and an operating address register (JBAR). For each of the pointers in a set relating to a digital buffer, a separate pointer register (JBSR, JBER, JBIR, JBOR) is provided and address data is input and stored substantially at the same time in each pointer register corresponding to a set of pointers. The subsequent address for reading/writting in the digital buffer memory (JBUM) is calculated and stored in at least the operating address register (JBAR).
