Abstract

An electronic device may be provided that includes a first processor and a second processor, the first processor to wirelessly receive a data packet from another device, and to determine a property (or type) of the received data packet. When the property or type of the received data packet is a first property or first type then the first processor to process the data packet. On the other hand, when the property or type of the received data packet is a second property or second type then the second processor to process the data packet.

Claims

1. An electronic device comprising:

a first processor; and

a second processor, the first processor to wirelessly receive a data packet from another device, and to determine that a type of the received data packet is a Bluetooth™

low energy (BLE) or non-BLE data packet type based on a header of the received data packet, and when the determined type of the received data packet is the BLE data packet type then the first processor is to process the data packet, and when the determined type of the received data packet is the non-BLE data packet type then the first processor is to provide the data packet to the second processor and the second processor to process the data packet.

2. The electronic device of claim 1, wherein the header of the received data packet is a Host Controller Interface (HCl) header or Logical Link Control and Adaptation Protocol (L2CAP) header.

3. The electronic device of claim 1, wherein the second processor is a host processor.

4. The electronic device of claim 1, wherein when the determined type of the received data packet is the non-BLE data packet type, the first processor is to wake up the second processor and to forward the data packet to the first processor.

5. The electronic device of claim 1, wherein the received data packet is a Bluetooth™

(BT) data packet and the first processor is to determine the type of the received data packet based on a header of the BT data packet.

6. The electronic device of claim 1, wherein the first processor and the second processor are to be provided on a silicon chip.

7. The electronic device of claim 1, wherein the first processor is to include a first software stack, and the second processor is to include a second software stack.

8. The electronic device of claim 7, wherein the first software stack is to include profile information related to the BLE data packet type, and the second software stack is to include profile information related to the non-BLE data packet type.

9. One or more non-transitory computer-readable media (NTCRM) comprising one or more instructions that when executed cause a first processor and a second processor to perform one or more operations to:

determine a type of a data packet received to be a Bluetooth™

low energy (BLE) or non-BLE data packet type at the first processor;

process the data packet at the first processor when the received data packet is determined to be the BLE data packet type;

provide the data packet to a second processor when the received data packet is determined to be the non-BLE data packet type; and

process the data packet at the second processor.

10. The one or more NTCRM of claim 9, wherein providing the data packet to the second processor includes waking up the second processor and forwarding the data packet to the first processor.

11. The one or more NTCRM of claim 9, wherein determining the type of the received data packet includes determining the type of the data packet based on a header of the data packet.

12. The one or more NTCRM of claim 9, wherein the first processor and the second processor are to be provided on a silicon chip.

13. The one or more NTCRM of claim 9, wherein the first processor is to include a first software stack, and the second processor is to include a second software stack, the first software stack to include profile information related to the BLE data packet type, and the second software stack to include profile information related to the non-BLE data packet type.
