US 12,301,697 B2 · Heterogeneous clock management solution

Abstract

Systems and techniques for an heterogeneous clock management solution for industrial systems are described herein. In an example, a system includes a clock management circuit adapted to receive core timing information from a core of an integrated circuit. The clock management circuit is further adapted to correlate the core timing information with a reference clock. The clock management circuit is further adapted to output frequency and time offset of the reference clock to the core timing information. The system includes an execution circuit adapted to schedule a transaction from the core at a scheduled time relative to the reference clock using the frequency and time offset. The execution circuit is further adapted to issue a command to execute the transaction at the scheduled time.

Dependent claims

A system for heterogeneous clock management, the system comprising:

a clock management circuit to:
receive core timing information from a core of an integrated circuit;
correlate the core timing information with a reference clock;
and
output, to the core of the integrated circuit, a frequency and time offset of the reference clock to the core timing information, for scheduling transactions with the core of the integrated circuit at an internal timing of the core of the integrated circuit relative to the reference clock.
