Embodiment Construction

[0040] exist figure 1 The system-on-chip device 1 shown in includes a first electronic component 2, a second electronic component 3, a central processing unit 4 as a third electronic component, a general purpose random access memory 5 as a fourth electronic component, and a multiplexer 6. The multiplexer is part of the system bus 7, and all these components are arranged on a common substrate 8 as an integrated circuit.

[0041]The first electronic component 2 is a wireless local area network transceiver, which is connected to a first external antenna 11 . It contains a first internal random access memory 9, for example, with a size of 2MBit as a buffer memory performing its special purpose communication function. The second electronic component 3 is a digital video broadcasting transceiver for handheld devices, which is connected to an outer second external antenna 12 . It contains a second internal random access memory 10 of 2MBit which acts as buffer memory for its special...

Abstract

The invention relates to a system-on-chip apparatus (1), comprising at least two electronic components (2, 3) serving for special purpose functions and a system bus (7) and at least one random access memory (9) that is integrated into the first electronic component (2), located in common on one substrate (8), wherein the system bus (7) connects the electronic components (2, 3) and wherein the random access memory (9) of the first electronic component (2) is time shareable to the second electronic component (3) via said system bus (7), and to a method for operating such a system-on-chip apparatus (1).

Description

technical field [0001] The present invention relates to a system-on-chip device comprising at least two special-purpose [0002] functional electronic components, and the invention relates to methods of operating such devices. Background technique [0003] A System-on-Chip (abbreviated SoC) device is the packaging of all the necessary electronic circuits, components and components of a "system" such as a mobile phone or digital camera on a single integrated circuit (IC), often referred to as a microchip. A system-on-chip device consists of general-purpose elements like processor cores, bus systems, and memory, as well as dedicated hardware elements or hardware accelerators. For example, a system-on-chip device for a sound detection device might include an audio receiver, an analog-to-digital converter (ADC for short), a microprocessor, memory, and input / output logic controls for the user—all on a single microcontroller. on chip. [0004] For example, a special purpose fun...
