摘要
A central processor unit (1) has a memory with zones (3,4). In a first memory zone (3), a series of executable functions are stored directly by the central unit (1). The first zone (3) is protected. The program is stored in a second memory zone (4) in the form of a series of instructions executable by the CPU, or the function contained in the first memory zone (3) is activated. The functions of the first zone of memory are executable at pre-determined addresses and besides activation of the functions of the first memory zone, the instructions of the second memory zone are exclusively executable in the second memory zone.
