Abstract

Claims (14)

1. A system comprising:

a first memory configured to store first layers of a Bluetooth protocol stack including at least a portion of a link manager layer;

a second memory configured to store second layers of the Bluetooth protocol stack, the second layers having higher real-time requirements than the first layers;

a host processor coupled to the first memory, the host processor configured to execute the first layers;

and a second processor coupled to the second memory, the second processor configured to execute the second layers, wherein the first memory and the second memory exclude a Bluetooth specified transport layer of the Bluetooth protocol stack.

2. The system of claim 1 , wherein the first memory and the host processor are on different chips.

3. The system of claim 1 , wherein the second memory and the second processor are on a single chip.

4. The system of claim 1 , wherein the second memory, the host processor, and the second processor are on a single chip.

5. The system of claim 1 , wherein the first layers comprise at least a portion of a host controller interface command and event handler layer.

6. The system of claim 1 , wherein the second layers comprise at least a portion of a link controller layer and at least a portion of a baseband firmware layer.

7. The system of claim 1 , further comprising:

a third memory coupled to the host processor, the third memory configured to store payload buffers.

8. The system of claim 7 , further comprising:

a fourth memory coupled to the second processor, the fourth memory configured to store payload buffers.
