Apple patents chip method to delay calls when processor is busy

This patent describes a method for a dual-core processor to handle incoming connection requests, or 'paging messages,' more efficiently. If the main processor core is too busy to respond to a call, the system calculates a new time for the secondary core to check for the message instead of failing immediately.

Why it mattersThis improves the reliability of wireless connections on devices like phones by ensuring the processor can respond to network signals even when it is handling other tasks.

In the filing’s own words

Techniques are described herein for smart page scanning through identifier sensing, An example method includes a first core receiving, by a first core of a first computing device, a first paging message from a second device at a first duration. The first computing device can determine that a second core of the first computing device is performing an operation that prevents completion of a paging process. The first computing device can determine a second duration for a second paging message based at least in part on determining that the second core is performing the operation. The first computing device can cause the second core to scan for the second paging message from the second computing device at the second duration. The second core can receive the second paging message at the second duration. The second core can transmit a paging response for establishing the connection with the second device.

What exactly they claim (claim 1)

1. A method performed by a first computing device, the method comprising: receiving, by a first core of the first computing device, a first paging message from a second computing device at a first duration, wherein the first computing device comprises a dual core architecture, and wherein the first core of the dual core architecture is a scan core; determining, by first computing device, that a second core of the first computing device is performing an operation that prevents completion of a paging process for establishing a connection with the second computing device, wherein the second core of the dual core architecture is a main core; determining, by the first computing device, a second duration for a second paging message based at least in part on determining that the second core is performing the operation that prevents completion of the paging process; causing, by the first computing device, the second core to scan for the second paging message from the second computing device at the second duration; receiving, by the second core of the first computing device, the second paging message at the second duration; and transmitting, by the second core of the first computing device, a paging response for establishing the connection with the second computing device.
