SYSTEM, METHOD AND ARTICLE OF MANUFACTURE FOR DATA TRANSFER ACROSS CLOCK DOMAINS

摘要

A system, method and article of manufacture are provided for data transfer across different clock domains. A request for transferring data from a sending (transmitting) process in a first domain to a receiving process in a second domain is received. The first domain and the second domain have different clocks. A channel circuit is created with handshaking and resynchoronization logic to help resolve metastability. The channel circuit is then used to transfer the data from the sending process to the receiving process.
