METHODS AND APPARATUS FOR CREDIT-BASED FLOW CONTROL

摘要

Methods and apparatus are provided for credit-based flow control. Techniques allow a receiver to provide buffer characteristic information to a sender using a single extended receiver ready signal. Multiple credits can be allocated using a single extended receiver ready signal as well. Counters and registers are used to allow for the accidental loss of extended receiver ready signals while still maintaining an accurate reflection of the types and numbers of buffers available.
