Title: UPDATE OF A KERNEL IN THE COURSE OF OPERATION
Abstract:
In order to update a kernel (2i) while an application program (3i) is being executed on a computer (40), a method (100) comprises the following steps: execution (110) of the application program (3i) on the computer (40) under a first kernel (2i) and with at least one base pointer (6i) that indicates a first data structure (51) that indicates routines of the first kernel (21); provision (120) of a second kernel (22) on a memory of the computer (40); provision (130) of a second data structure (52) on a memory of the computer (40), which second data structure indicates routines of the second kernel (22); changing (140) of the at least one base pointer (6i) to at least one base pointer (6i) that indicates the second data structure (52). Furthermore, the invention relates to an appropriate memory controller (10) for updating a kernel (2i) while an application program (3i) is being executed on a computer (40).
