Abstract

Embodiments of the present invention are directed to a wireless-enabled component (WEC) for enabling a wireless bus for intra-chip and inter-chip communication. A WEC encompasses a functional block of an IC (such as, for example, a processing core of a processing unit), an entire IC (such as, for example, a processing unit), or a device that includes a plurality of ICs (such as, for example, a handheld device). According to embodiments, a WEC may be associated with one or more sub-blocks of an IC, a single IC, or a plurality of ICs.

Claims

1. A wireless-enabled component (WEC), comprising:

a core module configured to perform one or more functions of the WEC;

a wireless transceiver, coupled via an interface to the core module, configured to transmit or receive a data signal wirelessly to or from another WEC;

a power interface configured to receive a modulated power signal, distinct from the data signal, from an external source and to provide power to the core module and the wireless transceiver; and

a demodulator, coupled to the power interface, configured to demodulate the modulated power signal to generate configuration information and to provide the configuration information to the wireless transceiver and the core module.

2. The WEC of claim 1, wherein the core module comprises one or more of:

a microprocessor, a microcontroller, a digital signal processor, a programmable logic circuit, memory, an application specific integrated circuit (ASIC), an analog to digital to converter (ADC), a digital to analog converter (DAC), and digital logic circuitry.

3. The WEC of claim 1, wherein the wireless transceiver includes one or more of:

a free-space RF transceiver, a waveguide RF transceiver, and an optical transceiver.

4. The WEC of claim 1, wherein the interface includes a wired connection.

5. The WEC of claim 1, wherein the interface includes a proximity coupling.

6. The WEC of claim 5, wherein the proximity coupling is an inductive coupling or a capacitive coupling.

7. The WEC of claim 1, wherein the power interface includes a wireless power interface configured to receive the modulated power signal wirelessly from the external source.

8. The WEC of claim 7, wherein the power interface includes one or more of:

an inductive coupler and a capacitive coupler.

9. The WEC of claim 8, wherein the power interface includes a coil.

10. The WEC of claim 1, wherein the modulated power signal is an amplitude modulated power signal.

11. The WEC of claim 1, further comprising:

an AC to DC converter, coupled to the power interface, configured to convert the modulated power signal from AC to DC and to provide DC power to the core module and the wireless transceiver.
