Method And Structure To Support System Resource Access Of A Serial Device Implementing A Lite-Weight Protocol
First Claim
1. A serial buffer comprising:
- a first path for processing normal data packets on the serial buffer;
a second path for processing priority packets on the serial buffer, wherein the second path includes a priority packet processor configured to implement accesses of on-chip resources of the serial buffer in response to the priority packets.

Abstract
On-chip resources of a serial buffer are accessed using priority packets of a Lite-weight protocol. A priority packet path is provided on the serial buffer to support priority packets. Normal data packets are processed on a normal data packet path, which operates in parallel with the priority packet path. The system resources of the serial buffer can be accessed in response to the priority packets, without blocking the flow of normal data packets. Thus, normal data packets may flow through the serial buffer with the maximum bandwidth supported by the serial interface. The Lite-weight protocol also supports read accesses to queues of the serial buffer (which reside on the normal data packet path). The Lite-weight protocol also supports doorbell commands for status/error reporting.
