Embodiment Construction

[0046] figure 1 A schematic diagram of a system on a chip 1 (system on chip - SoC) according to the invention is shown. Here, the system-on-a-chip 1 has, for example, four computing units 2 configured as computing cores, on which different operating systems and / or applications (application programs) can run, wherein a plurality of computing units 2 can be combined Assignment to an operating system / application and / or partial assignment can also take place, ie overall virtual computing components can be defined, for example via a hypervisor.

[0047] In order to provide RAM for the computing unit 2, the system-on-a-chip 1 also includes a storage unit 3, which has a storage space 5 allocated in a plurality of storage areas 4 for the computing unit 2, wherein the storage areas 4 pass through the monitoring pages 6 ( guardpages) separation. The memory access control unit 7 coordinates the access of the computing unit 2 to the storage unit 3 , and the memory access control unit ma...

Abstract

A single-chip system (1) is disclosed. The system has multiple computing units (2), in particular computer cores and / or CPUs, at least one input / output unit (9), a memory unit (3) and an input / outputcontrol unit (10) that coordinates the communication between the computing units (2) and the at least one input / output unit (9), wherein the single-chip system (1) further has an attack detection unit(14, 14a, 14b), produced as hardware, that is connected by means of a hardware signal connection (16) to at least the input / output control unit (10) as a component of the single-chip system (1) and evaluates input signals received from the input / output control unit (10) for a rule infringement in a set of attack detection rules (15), which rule infringement needs to be logged and / or responded towith at least one measure.

Description

technical field [0001] The invention relates to a single-chip system with a plurality of computing units, in particular computing cores and / or CPUs, at least one input / output unit, a memory unit and an input / output control unit, the input / output control unit coordinating Communication between the computing unit and at least one input / output unit. Furthermore, the invention relates to a method for operating such a single-chip system as well as to a motor vehicle. Background technique [0002] Single-chip systems, often also known as “system-on-chip” SoCs, have been proposed in the prior art. Usually, multiple computing units that can run in parallel, especially computing cores, are realized through such a system-on-a-chip, wherein other components of the system-on-a-chip provide storage space and input / output schemes (I / O), and are implemented in the Data exchange between components. An example of a component of a system-on-a-chip for such coordination of data exchange bet...
