Embodiment Construction

[0035] figure 1 A block diagram schematically shows a first embodiment of an interrupt request distribution device 100 according to the present invention, also referred to below as "distribution device 100" for short and in English as an interrupt router. The distribution device 100 has: an input 102 on which the distribution device can receive an input interrupt request signal irq_i from a source 10; and at least one output 112 for outputting an output interrupt request signal irq_o to a sink 200, which In particular, it can be a computing unit 200 such as a microcontroller with computing core 202 .

[0036] The source 10 may for example be a communication module of SPI or MCS type or similar, which outputs an input interrupt request signal irq_i to the dispensing device 100 eg when it has received data from an external unit (not shown). The distribution device 100 can then form a corresponding output interrupt request signal irq_o from at least one input interrupt request s...

Abstract

The invention relates to an interrupt request distributor, in particular for a computing unit having at least one computing kernel, wherein the interrupt request distributor has at least one input terminal for receiving input interrupt request signals and at least one output terminal for outputting output interrupt request signals, in particular to the computing unit, wherein the interrupt requestdistributor is configured to form at least one output interrupt request signal according to at least one input interrupt request signal, the interrupt request distributor being characterized in thatthe interrupt request distributor comprises a delay means configured to delay an input interrupt request signal by a predetermined delay time so as to obtain a delayed interrupt request signal and tooutput the delayed interrupt request signal as the output interrupt request signal to the at least one output terminal.

Description

technical field [0001] The invention relates to an interrupt request dispatching device, in particular to an interrupt request dispatching device for a computing unit having at least one computing core, wherein the interrupt request dispatching device has at least one input for receiving an incoming interrupt request signal and at least one For outputting an output interrupt request signal, in particular to an output of a computing unit, the interrupt request assignment device is designed to form at least one output interrupt request signal as a function of at least one input interrupt request signal. [0002] The invention also relates to an operating method for such an interrupt request dispatching device. [0003] The invention also relates to an electronic functional module, which is designed to generate at least one interrupt request signal for at least one further component, in particular a computing core of a computing unit, and to an operating method for such an electr...
