Abstract
The invention concerns a program-controlled device with reloading possibility for and change-over possibility to a second operating system (GLS1, GLS2, GLS3, GLSx) without program interruption, with a processor and a program memory which the processor can address via address lines, where a switchable change-over switch is provided in the address lines whereby two memory areas (01xx, 10xx) can be exchanged with each other by means of translation.
Claims2
A program-controlled device with reloading possibility for and change-over possibility to a second operating system (GLS1, GLS2, GLS3, GLSX) without program interruption, with a processor (μC) and a program memory (DRAM) which the processor can address via address lines (A/D0-15, A16-A19), characterized in that a switchable change-over switch (ASL) is provided in the address lines, whereby two memory areas (01xx, 10xx) can be exchanged with each other by means of translation, wherein the switchable change-over switch exchanges two address lines (A19, A18) with each other.
