    摘要: A method and system to enable power measurements of a system-on-chip in various modes. In one embodiment of the invention, the system-on-chip has full controllability of its logic and circuitry to facilitate configuration of the system-on-chip into a desired mode of operation. This allows hooks or interfaces to access the system-on-chip externally for measurements. For example, in one embodiment of the invention, the hooks in the system-on-chip allow a backend tester to configure the system-on-chip into various modes easily to perform power consumption measurements of one or more individual components of the system-on-chip. The power consumption measurement of the individual components in the system-on-chip can be performed faster and can be more accurate. In addition, the overall yield of the SOC can be increased as it is easier to detect failure parts.

    摘要: Detecting and flushing maximal length packets is set forth herein. In one embodiment, the method comprises receiving a flushing event and, in response to the flushing event, repeatedly detecting a maximum length packet of write data from a write combining storage area and flushing the detected maximum length packet to a target input/output (I/O) device over a bus. Each maximal length packet is a packet of maximum payload of write data that can be formulated within in the write combining storage area while adhering to packet protocol rules for the bus.
