Abstract
A processing of data in cooperation with a memory (MEM), for example an MPEG decoding, has the following characteristic features. A processor (P) generates a logic request (LRQ). The logic request (LRQ) defines at least one characteristic (CAR) common to a group of data (GRP). An addressing circuit (AGA) generates a physical request (PRQ) on the basis of the logic request (LRQ). The physical request (PRQ) defines memory (MEM) addresses (A) relating to the group of data (GRP). A memory interface (INT) effects a transfer (TRNSFR) of the group of data (GRP) between the memory (MEM) and the processor (P) on the basis of the physical request (PRQ). Thus, the processor need not know how and where the data to be processed or having been processed are stored in the memory. This facilitates the design of a data processing device and, particularly, a family of such devices.
