Embodiment Construction

[0034] figure 1 A schematic diagram of an authorization list 21 stored in a read-only data memory 26 is shown in one embodiment of the single-chip system 10 according to the invention. Authorization list 21 includes as protection system 20 (see Figures 2 to 5 A plurality of entries 22 of components of ), each corresponding to a permitted access.

[0035] Each entry 22 has a tuple comprising the ID 23 of the processor 11, 12 of the system-on-a-chip 10, the ID 24 of the control unit 15, 16, 17 of the system-on-a-chip 10 and the ID assigned to the control unit 15, 16, 17. The address range 25 of the peripheral device 40,50. The tuple also includes the maximum frequency of access (not shown) granted by the control unit 15 , 16 , 17 with ID 24 to the processor 11 , 12 with ID 23 .

[0036] Only four entries 22 are shown here by way of example, wherein the first entry 22 defines an address range 25 shared by all processors 11 , 12 for the control units 15 , 16 , 17 , while the r...

Abstract

The invention relates to a system on chip (SoC) for a control device of a vehicle having at least one bus, having at least one control unit (controller, Ctrlr) connected to the at least one bus, for controlling a peripheral device associated with the at least one control unit, and having multiple processors (central processing unit, CPU) connected to the at least one bus.

Description

technical field [0001] The present invention relates to a single-chip system (system on chip, SoC) for a control device of a vehicle, comprising: at least one bus; at least one control unit (controller, Ctrlr) connected to the at least one bus, the at least one control Units for controlling peripherals assigned to at least one control unit; and a plurality of processors (central processing units, CPUs) connected to at least one bus. Background technique [0002] Single-chip systems integrate several components of a computer into one component and are increasingly used in modern vehicles, for example in central control units (Electronic Control Unit, ECU), which are used to control the different functional systems of the vehicle . The functional systems of a vehicle include, on the one hand, safety systems, which relate to the driving safety of the vehicle, such as the engine control or the braking system, and, on the other hand, comfort systems, which increase the comfort o...
