Arbiter for Logical to Physical Frame Conversion

摘要

A method and apparatus for generating logical frames from arbitrating among packets is disclosed. An integrated circuit (IC) includes an arbitration circuit configured to generate a logical frame having a first number of bytes by selecting at least one a plurality of packets received from different functional circuit blocks. At least one of the plurality of packets is of a different data size than at least one other one of the plurality of packets. The arbitration circuit is configured to, when selecting two or more of the plurality of packets, generate the logical frame by concatenating selected packets together. The IC further includes a framing circuit configured to generate, based on the logical frame, a physical frame for an outgoing transmission over a serial communications link, wherein the physical frame comprises a second number of bytes that is less than or equal to the first number of bytes.
