ABSTRACT:
The invention herein pertains to a data processing device (1) with a processor (2) and a memory (3). The memory (3) comprises a first memory sector (4) and a second memory sector (6), a first cache (5) being arrayed for the first memory sector (4) and a second cache (7) being arrayed for the second memory sector (6). It is the function of the second cache (7) that predetermined and selected sub-programs, interrupt vectors (8) and interrupt handlers (9), which are normally stored in the second memory sector (6), which is, for example, a ROM memory or a RAM memory, are saved in temporary storage in the second cache (7). It is an advantage that no displacement cycles take place in the second cache (7).
