Approaches, techniques, and mechanisms are disclosed for monitoring and reporting status information in a computing device. According to one embodiment, status messages are generated with respect to a subsystem of a computing system, such as a computer chip configured to perform network switching and routing functions in a network device. The status messages convey status information, such as configuration and/or operational states, metrics, or other statistics. A message decoder within the system may be configured to receive and analyze the status messages. Based thereon, the message decoder generates output data in a specific format that controls an output device, such as an LED array. The message decoder then sends the output data to the output device. Enabling the reporting of status information through LED indicators and other typically custom and proprietary output devices is thus greatly simplified. A status chain for collecting and reporting status information is also described.

Hardware-assisted monitoring and reporting

In some applications, such as video motion compression processing for example, a request pattern or 'stream' of requests for accesses to memory (e.g., DRAM) may have, over a large number of requests, a relatively small number of requests to the same page. Due to the small number of requests to the same page, conventionally sorting to aggregate page hits may not be very effective. Reordering the stream can be used to 'bury' or &#x201c;hide&#x201d; much of the necessary precharge/activate time, which can have a highly positive impact on overall throughput. For example, separating accesses to different rows of the same bank by at least a predetermined number of clocks can effectively hide the overhead involved in precharging/activating the rows.
