Data Synchronization For Circuit Resources Without Using A Resource Buffer
First Claim
Patent Images
1. A method of resource-synchronizing data transmitted on a communication link between a first device and a second device, the communication link having at least one data lane, wherein the second device has a resource that is accessible based on an access schedule, the method comprising:
- determining a timing offset based on the access schedule of the second device;
communicating the timing offset to the first device, anddelaying transmission of data from the first device to the second device through the communication link by the timing offset so that the data is received at the resource when the resource is accessible according to the access schedule.

Abstract
A resource synchronizer synchronizes transmission of data to a SerDes of a device so that the SerDes is capable of providing the data to a resource of the device without buffering the data between the SerDes and the resource.

11. An apparatus comprising:
-
a memory having an access schedule; a SerDes coupled to the memory; and a resource synchronizer configured to determine a timing offset for transmission of data to the SerDes so that the SerDes is capable of forwarding the data to the memory according to the access schedule without the need for buffering the data between the SerDes and the memory. - View Dependent Claims (12, 13, 14)

15. An electronic communication system, comprising:
-
a first device for communicating information; and a second device coupled to the first device via a communication link, the second device comprising a SerDes and a resource coupled to the SerDes, the resource having an access schedule for accessing the resource, wherein the second device in configured to determine a timing offset for delaying transmission of training sequence from the first device to the second device so that the SerDes is capable of providing the data to the resource according to the access schedule without the need for buffering the data between the SerDes and the resource once training is complete. - View Dependent Claims (16, 17, 18, 19, 20)
