Abstract
In order to allow an external memory space to enter into the memory space of a microprocessor (43) comprising a cache memory (94), an integrated circuit (42) serves as an interface between the microprocessor (43) and a memory unit (8, 9, 12) constituting the external memory space. The integrated circuit (42) comprises a stack (91) sized for containing a data block from the memory unit (8, 9, 12) such that the block from the memory unit (8, 9, 12) is seen as one or more blocks in the cache memory (94), and a register (93) belonging to the memory space of the microprocessor (43) adapted to contain the coordinates for access to the memory unit (8, 9, 12).
